Edit randomization alert

Randomization is a process to help you avoid potential bias in the selection and allocation of subjects arising from the predictability of treatment assignments. From a statistical perspective, randomization provides unbiased estimates of error variance and independence of errors. A randomization alert is a customizable notification mechanism that generates an email to inform relevant parties when a normal or forced subject randomization succeeds or fails.

The purpose of a randomization alert is to promptly notify the responsible IWRS users about the subject randomization. You can update the details of the created randomization alert when you need to change the basic information or email settings.

To edit the randomization alert

  1. In the IWRS application header, select the ALERT tab.

  2. On the page that opens, from the left pane, select the subtab corresponding to the alert category of your interest.
