Data given as mean, ±standard deviation. ^{a}Coefficient from a linear regression model with followup values as a dependent variable and baseline values as a covariate.^{b}P values, which were derived from linear regression models with baseline values as a covariate, are for the differences in mean between intervention and control group.
