Medical journals still worship at the altar of frequentist statistics with the p-value being the holy grail. Bayesian statistics are being considered now, especially in oncology studies since a myriad of combinations of different drugs must be evaluated.
Also, rejecting the null hypothesis with a statistically significant p-value doesn’t prove the drug you’re testing is the cat’s pajamas. We have “fiction” and “non-fiction” books, not “fiction” and “truth” books. Strictly speaking, in the criminal justice system folks are “innocent” (the null hypothesis) or “not-innocent.”
