Short term effects of a weight loss and healthy lifestyle programme for overweight and obese men delivered by German football clubs

Results were based on Intention-to-treat (ITT) analysis with Multiple Imputation.. After 12 weeks, the mean weight loss of the intervention group adjusted for club, course and participants' age was 6.24 kg (95 % CI 5.82 to 6.66) against 0.50 kg (-0.47 to 1.49) in the comparison group (p
