- pcrh 12y agoThe point of statistical tests is to assess the accuracy of a prediction. These trials were not designed to predict/test the efficacy of the drug, therefore no conclusion regarding efficacy can be drawn. It is of course possible that there was a real effect, and that this is reflected in the data gathered, however to determine if that is the case another trial has to be performed.
