Meta-analysed effects on homeostatic model assessment of insulin resistance (HOMA-IR) and free androgen index (FAI) expressed as population mean effects in control and exercise groups, and as modifying effects of exercise duration, baseline, and dietary co-intervention.

Evaluated at mean baseline (HOMA-IR=moderate, FAI = 8.4%), training time = 30 h, and no dietary co-intervention.
Modifying effect of baseline is evaluated for high versus low baseline.
Modifying effect of baseline is evaluated for a 3.0-fold difference in baseline.

Effects are shown with their observed magnitudes, determined by standardisation. Clear effects are show with the probability of either a true substantial change (*possibly, **likely, ***very likely) and/or a true trivial change (00likely, 000very likely). Magnitudes in bold are clear with 99% compatibility intervals.
