aStatistically significant differences were found between groups for the follow-up values [generalised linear models (GLM)], repeated measures; p < 0.05)
bStatistically significant differences were found for the follow-up values in each group (GLM, repeated measures; p < 0.05). No statistically significant differences were found between groups for the follow-up values in each visit (GLM, repeated measures; p < 0.05).
