Background In medical papers today there usually are several statements based on the result of hypothesis tests presented, along with the associated p values. That would not have meant that there was no difference between the two treatments, but only that, with the given small sample size there is not enough evidence to reject H 0. The only question that the p value addresses is, does the experiment provide enough evidence to reasonably reject H 0.
