## Selection Probabilities File Parameters
​
The Selection Probabilities file is optional. This file must be specified if requesting propensity score analyses for exposed and unexposed/comparator pregnant cohorts in the report. This file defines the selection probability for each comparison and subgroup.
The Selection Probabilities file is optional. This file must be specified if requesting adjustment for selection bias when conducting propensity score analyses for exposed and unexposed/comparator pregnant cohorts. This file defines the selection probability for each comparison and subgroup.

​
| **Parameter** | **Field Name** | **Description** |
| --- | --- | --- |
|Group Name for Analysis|ANALYSISGRP|Name to differentiate exposure of interest/reference pairs. <br> <br> **Note 1:** ANALYSISGRP must correspond to values of ANALYSISGRP included in the L2 Comparison File. <br><br> **Format:** SAS character $40; no special characters (e.g., commas, periods, hyphens, spaces, etc.) allowed, and underscores must be used to mark spaces. <br> **Example:** drug_a_and_drug_b|
|Group Display Order|ORDER|Unique number for each ANALYSISGRP. This is used to determine the order of ANALYSISGRPs in the report. All ANALYSISGRPs should receive a unique ORDER value. ORDER values should start at 1 and be contiguous. <br><br>  **Format:** Numeric <br> **Example:** 1|
|RunID Corresponding to ANALYSISGRP|RUNID|RunID assigned to the run that corresponds to the specified ANALYSISGRP. <br> <br>  **Format:** SAS character $5<br> **Example:** r01|
|Subgroup identifier|COVARNUM| Subgroup covariate number <br> <br>  **Format:** SAS character $4<br> **Example:** 1000|
|Subgroup Value|Value| Subgroup value <br><br>  **Format:** SAS character $10<br> **Example:** M|
|Selection Probability among Exposed|S11|Probability of case selection among the exposed. <br><br> **Note 1:** if specified, odds ratio and 95% CI will be adjusted for selection probability. If left blank, non-adjusted OR will be produced. <br><br> **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Unexposed|S01|Probability of case selection among unexposed.<br><br> **Note 1:** if specified, odds ratio and 95% CI will be adjusted for selection probability. If left blank, non-adjusted OR will be produced. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Exposed|S10|Probability of non-case selection among exposed.<br><br> **Note 1:** if specified, odds ratio and 95% CI will be adjusted for selection probability. If left blank, non-adjusted OR will be produced. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Unexposed|S00|Probability of non-case selection among unexposed.<br><br> **Note 1:** if specified, odds ratio and 95% CI will be adjusted for selection probability. If left blank, non-adjusted OR will be produced. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Exposed|S11|Probability of case selection among the exposed. Odds ratio and 95% CI will be adjusted for selection probability. <br><br> **Note 1:** S11 is required to be specified if any . <br><br> **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Unexposed|S01|Probability of case selection among unexposed. Odds ratio and 95% CI will be adjusted for selection probability.<br><br> **Note 1:** S01 is required to be specified. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Exposed|S10|Probability of non-case selection among exposed. Odds ratio and 95% CI will be adjusted for selection probability.<br><br> **Note 1:** S10 is required to be specified. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|
|Selection Probability among Unexposed|S00|Probability of non-case selection among unexposed. Odds ratio and 95% CI will be adjusted for selection probability.<br><br> **Note 1:** S00 is required to be specified. <br> <br>  **Format:** Numeric<br> **Example:** 0.20|

This note is a bit confusing to me - why would somebody have a row in the file with these parameters missing? I would suggest adding a note that all 4 selection probabilies should be specified (i.e. you can't partially adjust)
