Note: Change values were calculated so a negative number represents a reduction from baseline value. Standardized coefficients are reported. Single predictor models were adjusted for age, baseline weight, and treatment condition. Multiple predictor models were adjusted for age, baseline weight, treatment condition and all variables listed.
