I am trying to learn how to interpret clinical study results. It seems that the confidence intervals and p-values suggest there is high degree of certainty in the results. Still, the odds ratio seems to have marginal improvements over the control, 4-8% depending on what was being measured. If I'm interpreting this study correctly, exercise has a marginal impact on adolescents mental health. I kind of hope I misread that study, and that exercise plays a larger role. If I read a study that tells me I may see a 4% chance of improvement if I make significant changes to my lifestyle, the chances that I ignore that study are about 96%. Guess, when viewed on aggregate a 4-8% improvement would be a valuable improvement.
