a
Estimated coefficient (βˆ) for treatment effect (UOT vs. SS) followed by standard error (SE). The dependent variable=post-pre of measure with pre-test score, age, gender, Full Scale IQ, mother/father education included as covariates. The coefficient is the estimated effect of a 1-point increase in the covariate on pre-post change score of the outcome measure.
