Use Experimental Event Rate (EER) to Generate Epidemiological Measures

Experimental event rate (EER) is used with control event rate (CER) to generate measures of absolute risk reduction (ARR) or absolute risk increase (ARI). ARR and ARI are then used to calculate either number needed to treat (NNT = 1/ARR) or number needed to harm (NNH = 1/ARI). http://www.scalelive.com/experimental-event-rate.html
