Readmission-free Kaplan–Meier curves. Cumulative readmission-free Kaplan–Meier curves of geriatric patients discharged home following a hospital admission for an acute medical illness. None of the patients died during the 30-day intervention period. Dropouts (n = 8) are excluded. Patients were randomized to 20 g twice daily whey protein supplementation (W) for 30 days, twice daily isocaloric placebo (P) for 30 days, intensive rehabilitation (R) 3 times weekly for 30 days, combined intensive rehabilitation plus whey protein (R + W) for 30 days, combined intensive rehabilitation plus placebo (R + P) for 30 days, or single testosterone injection at discharge (T). AIG: all intervention groups.
