Because only a few patients had a baseline 7-point ordinal score of 3, the patients with a baseline score of 2 and 3 were combined for the analysis. Categorical variables were presented as numbers (%). Ordinal variables were compared between groups using a proportional odds model. A p value of < 0.05 was considered statistically significant.
