Abstract

We conducted a simulation study to illustrate that P values can suggest but not confirm statistical significance; and they may not indicate epidemiological significance (importance). We recommend that researchers consider reporting effect sizes as P values in conjunction with confidence intervals or point estimates with standard errors to indicate precision (uncertainty).
