Changes in post-pre values are absolute and not adjusted. Values are means with standard deviation presented for each group (completers). Differences are estimated as the difference between means (SE), with 95% confidence intervals, based on the 1-factor analyses of covariance with the level at baseline and sex as a covariate. *Significant change.
