Add new cohort inclusion criteria
Inclusion criteria are the key characteristics of the target population that researchers will use to answer their research questions. Typical inclusion criteria include demographic, clinical, and geographic characteristics.
In IWRS, you can add inclusion criteria to your cohorts so that the subjects are divided into treatment groups based on your predefined factors and following your study objectives.
-
In the IWRS application header, select the TREATMENT DESIGN tab.
-
On the page that opens, in the left pane, select the Period subtab.
-
In the Period List table that appears, locate the period of your interest. Then in the Period Name column, select the value to open the period configurator.
