WebProf. Mary Ferrill explains how to calculate RR, RRR (Relative RIsk Reduction), ARR (Absolute Risk Reduction), and NNT/NNH. She starts this video with a table about the exposure and outcome for treatments. We can use this to help us calculate the parameters in the example in this video. WebCalculation To calculate the NNT, you need to know the Absolute Risk Reduction (ARR); the NNT is the inverse of the ARR: NNT = 1/ARR Where ARR = CER (Control Event Rate) – EER (Experimental Event Rate).

In a person with an AR of stroke of only 0.025 without treatment, the same treatment will still produce a 20% RRR, but treatment will reduce her AR of stroke to 0.020, giving a much smaller ARR of 2.5% – 2% = 0.5%, and an NNT of 200. Web7 mrt. 2024 · NNTs can be easily computed from an estimated risk difference (RD), risk ratio (RR), or odds ratio (OR) and a given baseline risk (Higgins et al., 2024, section 15.4.4).
