Control Event Rate Calculator

Posted by Dinesh on

This calculator calculates the control event rate using total number of patients treated, number who achieved at least 50% pain relief values. The term experimental event rate (EER) is used to describe the rate that good events occur with ibuprofen (22/40, or 55%) and control event rate (CER) to describe the rate that good events occur with placebo (7/40 or 18%).

Control Event Rate Calculation

Formula:

CER = Pn

Where,
CER is Control event rate (event rate with placebo)
PT is Total number of patients treated
Pn is Number who achieved at least 50% pain relief
