[Reports of interventions should provide] busy clinical readers with three sorts of information (complete with their confidence intervals): at least one absolute measure of efficacy (such as the number of patients who would need to be treated to prevent an event), the susceptibility of control patients to the target outcome (as a starting point for extrapolation to their own patients), and (although they could calculate it from the former two) some relative measure of efficacy (such as the relative risk reduction).
