"By convention, p-value ≤0.05 is considered statistically significant. It should be noted that statistically significant is not the same as clinically significant as this implies the p-value is a measure of treatment effectiveness which it is not."
"if a p-value is equal to or below the p-value cutoff, this does not mean that the results of the study are valid or that a study is meaningful; it only tells you that the difference between the mean values of the test group and control group would occur by chance only ≤5% of the time"
"e.g. a study that shows 1% increased enhancement with a new MRI imaging agent at p=0.001 is not nearly as interesting as a new imaging agent that shows 20% increased enhancement at p=0.05; however, in the former study there is a considerably reduced probability that the observed difference occurred by chance"
