The tyranny of the P-value: effect size matters

Psychiatry and Clinical Psychopharmacology, 2021
Statistical significance does not necessarily imply clinical significance. A P-value of less than 0.05 does not guarantee that the result will be important. Effect size needs to be calculated in order to appraise clinical relevance.

Statistical significance—meaningful or not [PDF]

Law, Probability and Risk, 2018
Statistical tests with large sample sizes can have large power. Power is the ability to detect an effect. Detection is indicated by a result which is statistically significant. A test with large power will detect a very small effect. This very small effect may not be meaningful in the context of the analysis being conducted.
