Analysis of repeated measures of FIQ score in both groups at evaluation visits throughout intervention
| Visits | Cannabis | Placebo |
|---|---|---|
| V1 | 57.50 (12.91)* | 58.56 (19.78) |
| V2 | 48.88 (19.21)*,† | 51.67 (17.59) |
| V3 | 47.75 (16.75)*,† | 52.33 (23.44) |
| V4 | 42.13 (17.18)† | 58.11 (19.79) |
| V5 | 43.25 (24.41)*,† | 53.44 (21.14) |
Analysis of repeated measures (distinct symbols represent significant differences between the moments in the mean values)
The mean score on the FIQ in both groups was maintained during most of evaluation visits throughout intervention; there was no significant variation in subsequent visits, except between visit 1 and visit 4 in the cannabis group (P = 0.032). In the placebo group, no difference was observed between moments.
FIQ = Fibromyalgia Impact Questionnaire; V1 = first visit; V2 = second visit; V3 = third visit; V4 = fourth visit; V5 = fifth visit; ; sd = standard deviation
