Fig. 1: Group means with confidence intervals that overlap.
Fig. 2: Confidence intervals and comparison of 2 group means (hypothetical clinical trial data: SEA = SEB = 1.8, means differ by 3 SE; assuming n >> 30 and independent samples, the 2-sided p value for testing the difference in means is approximately 0.036). SE = standard error of the mean.
