Data are mean % (s.d.) of improvement for HD and for PLI after 12 months. Differences between treatment groups were assessed by Analysis of Covariance (ANCOVA) on log-transformed values by adjusting for baseline values. Estimates were provided as mean percentage change over baseline (90 % CI). P-values are one-tailed. *P < 0.05; Shading = best improvement within groups.
