Obesity

Predictors of BMI reduction with phentermine/topiramate in adolescents with obesity

Int J Obes (Lond)Published Secondary analysis of a randomised controlled trial

Authors' conclusion

Baseline characteristics were not predictive of BMI reduction with either dose of PHEN/TPM compared to placebo in adolescents with obesity.
