Values are presented as means ± SD (95% confidence interval) or median (25%,75%) (if data are not normally distributed). a: Significant difference between baseline and three months in the same group; b: Significant difference between baseline and six months in the same group; c: Significant difference between three and six months in the same group; d: The difference value between three months and baseline values was significant between the two groups; e: The difference value between three months and six months values was significant between the two groups. Bolded values are significant.
