Data presented as mean, ±standard deviation, unless otherwise stated. aCoefficient from a linear regression model with follow-up values as a dependent variable and baseline values as a covariate. bP 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. Percentages are calculated based on number of participants available for follow-up.
