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

Difference in percent change in BMI from baseline to 56 weeks by PHEN/TPM dose relative to placebo (treatment effect) by predictor subgroups. The interaction p value corresponds to a test of different treatment effect between predictor subgroups for a given PHEN/TPM dose.
