  1. Data are analyzed by ‘Repeated measurement analysis’. Scores presented as means (SE). BL baseline score, ΔBL-3 months difference between 3 months and baseline. ΔBL-6mnd difference between 6 months and baseline. Effect M-C: difference ΔBL-6 months Medido – ΔBL-6 months Control.
  2. a. p-value based on ‘time x measurement’ analysis of difference score between baseline and follow-up.
  3. b. effect size: (effect M – C) / (SD of Medido group at baseline).
