Sensitivity analysis Due to wide variability in timing of the post treatment visits we also performed a linear regression analysis using the treatment groups as predictors and using VAS pain score at the follow-up visits as outcomes with and without adjustment for time to follow-up (days), the adjusted models showed a possible trend at the first follow-up visit ( p = 0.06) and were significant for the other follow-up visits ( p < 0.05).
