a
Adjusted linear regression models control for age, intervention group, evaluator, and all other statistically significant variables in the multivariable model.
b
NS=not significant.
c
SES=socioeconomic status, where the first quartile corresponds to the poorest SES and the fourth quartile corresponds to the highest SES.
