INCA statistics

[olle]

Statistics should be calculated from the data obtained from INCA at regular intervals in the form of a tab-separated file. Entries with personal numbers are regarded as accrued to the SCAN-B project, while those without are regarded as not accrued. It should be possible to specify a start and end date defining a time interval for the data used for the statistics.

The following statistics should be reported:

1. Percentage values of entries accrued with specimen, accrued without specimen, and not accrued.
2. Percentage sets of all diagnoses, accrued, and accrued with specimen for:
   a. ER Status (% positive and negative).
   b. PgR Status (% positive and negative).
   c. HER2 Status (% positive and negative).
   d. Age (years) (% >70, 50-70, <50).
   e. NHG (% Grade 3, Grade 2, Grade 1).
   f. Tumor Size (mm) (% >20, 10-20, <10).

Ticket accepted.

Traceability note:

• Creation of a csv file to be used when requesting information from the INCA database was introduced in Ticket #487 (Export information intended for INCA). The entries with personal numbers in the INCA csv file are defined in this file.
• Import of an INCA csv file was introduced in Ticket #525 (Import data from INCA). This ticket contains information on the INCA csv file and its processing of interest to this ticket.

[olle]

Design note:

• INCA file header columns to be used for filtering and statistics data, in addition to the columns used for INCA import:

Column contents	Column header
Diagnose date (for time period filter)	A030DiaDat
ER Status	A100ER_Värde
PgR	A100PR_Värde
HER2 Status	A100HER2_Värde
Age (years)	A000Alder
NHG	A100NHG_Värde
Tumor Size (mm)	A090HistoTumStl

Design discussion:

Much functionality needed for INCA statistics have already been implemented for INCA import, e.g. reading INCA *.csv files, checking input, mapping entries to SCAN-B database items, etc. (see Ticket #525 "Import data from INCA" for details), so it seems natural to expand the IncaServlet to cover INCA statistics too. However, in order to implement this, some existing methods need to be extended with new arguments and extra functionality, and methods used both for import and statistics might need to be renamed, so as not to refer specifically to "INCA import" unnecessarily.

Design discussion:

• As the details on entry selection and report layout for INCA statistics are not completely decided at the current time, these functions will at least initially be managed by separate methods for INCA import and statistics.
• When collecting data for the statistics calculations, a number of entries falls in the category "N/A":
  a. Entries with an integer value corresponding to a measurement/inspection having been performed, but with inconclusive result.
  b. Entries with an integer value corresponding to no measurement/inspection having been performed.
  c. Blank entries for the variable of interest.
• In the first version of the INCA statistics module, the number and percentage of "N/A" entries will be presented together with data corresponding to specific values, allowing the user to estimate the size of this "grey" group. However, in order to facilitate comparison with previously published data, where no "N/A" group is included, three numbers will normally be presented for each statistics entry:
  a. Percentage excluding "N/A" entries (enclosed in square brackets in report file, e.g. "[46.77%]").
  b. Percentage including "N/A" entries (e.g. "41.57%").
  c. Number of items (enclosed in parentheses, e.g. "(1376)").

(In [3963]) Refs #888. First (experimental) version of INCA statistics. It allows an INCA *.csv file in tab-separated format plus start and end date for the statistics calculation to be selected, after which a simple file check or a statistics calculation can be performed. Results are presented on the screen and in a created report file, which can be downloaded by clicking on a button in the web form.

1. JSP file index.jsp in resources/ updated in section "Personal information wizards", sub-section "Export/import information to/from external registers", with new entry "INCA statistics" coupled to new JSP file inca-statistics.jsp in resources/personal/. It requires "PatientCurator" role to be used, since it needs access to an INCA file with sensitive data.
2. New JSP file inca-statistics.jsp in resources/personal/ added. It is coupled to new javascript file inca-statistics.js in resources/personal/.
3. New javascript file inca-statistics.js in resources/personal/ added. It allows an INCA *.csv file in tab-separated format plus start and end date for the statistics calculation to be selected, after which a simple file check or a statistics calculation can be performed. Results are presented on the screen and in a created report file, which can be downloaded by clicking on a button. Servlet requests are made to java servlet IncaServlet. Requests related to the report file are accompanied with parameter reporttype being set to value "statistics".
4. Java servlet class/file IncaServlet.java in src/net/sf/basedb/reggie/servlet/ updated with functionality for INCA statistics:
   a. New String constants REPORT_TYPE_STATISTICS, INCA_STATISTICS_REPORT_FILENAME, and STATISTICS_PROGRESS_ID defined. Constant REPORT_TYPE_STATISTICS is set to value "statistics".
   b. Private method String fetchReportFileName(String reportType) updated to return new String constant INCA_STATISTICS_REPORT_FILENAME for argument reportType having value REPORT_TYPE_STATISTICS.
   c. Private method JSONObject fetchKeyColumnIndexes(List<String> headerList, JSONObject jsonIncaFileProp) updated to return information on indexes for key columns of interest for INCA statistics.
   d. Protected method void doPost(HttpServletRequest req, HttpServletResponse resp) updated with new command "IncaStatistics". Much from command "ImportInca" is reused, but an initial entry date selection is performed using diagnose dates, after which INCA entry lines both with and without personal numbers are collected. Mapping of entry lines to database items is performed by new private method LineDatabaseMappingForStatisticsResult LineDatabaseMappingForStatistics(DbControl dc, List<IncaEntryLine> incaEntryLines, ...). A JSONObject jsonIncaStatistics with INCA statistics is obtained by calling new private method JSONObject incaStatistics(...). JSONObject jsonIncaStatistics is added to JSONObject jsonIncaFilePropDetails and to the returned JSONObject. The report file is obtained by calling new private method void createIncaStatisticsReportFile(JSONObject jsonIncaFilePropDetails, String message).
   e. New private method List<String> filterIncaLinesByDate(int filterDateClmIndex, Date startDate, Date endDate, List<String> lines) added. It filters a list of INCA file lines by removing lines not within allowed time period.
   f. New private method LineDatabaseMappingForStatisticsResult lineDatabaseMappingForStatistics(DbControl dc, List<IncaEntryLine> incaEntryLines, ...) added. It performs database mapping and data value check on a list of INCA entry lines intended for INCA statistics. The result includes a list of lines of accrued entries with specimens.
   g. New private inner class LineDatabaseMappingForStatisticsResult added. It contains two private attributes with public accessor methods, LineDatabaseMappingResult lineDatabaseMappingResult and List<IncaEntryLine> accruedWithSpecimenEntryLineList.
   h. New private method JSONObject incaStatistics(List<IncaEntryLine> nonAccruedIncaEntryLines, List<IncaEntryLine> accruedIncaEntryLines, List<IncaEntryLine> accruedWithSpecimenEntryLines, JSONObject jsonIncaFileProp) added. It calculates INCA statistics and returns the results in a JSONObject.
   i. A number of private convenience methods supporting method incaStatistics(...) in performing the statistics calculation are added. They support statistics for variables having positive/negative status, grade selection, and selection of integer values in different groups depending on value.
   j. New private method void createIncaStatisticsReportFile(JSONObject jsonIncaFilePropDetails, String message) added. It creates a report file with INCA statistics, corresponding to the data shown in the web form.

Functional specification update:

• The results of an INCA statistics calculation should be stored in a *.csv text file in tab-separated format, in addition to the existing report file. The first version of this CSV file should contain the following columns:

Header	Example
Property	ER Status
Selection	All Diagnoses
ValueName	Positive (% excl. N/A)
ValueType	Float
Value	86.131935

In general a row in the *.csv file corresponds to a single data value. When used to store information on e.g. statistics parameters or the used INCA file, some columns (normally the "Selection" column) might be empty.
