Clinicians often assume that if a P-value is below 0.05 then the result must be important. Moreover, there is often the false belief that a P-value of less than 0.0001 denotes an even more impressive difference. Dr. Citrome will discuss how simple to calculate measures of effect size such as number needed to treat (NNT) and number needed to harm (NNH) can help clinicians place study outcomes in a more relevant clinical context.
