Table 5.
Generalized ordinal logistic regression assessing the association between the total number of comorbid conditions (dependent variable) and WPI, pain duration, sick leave, and BMI in pain groups.

WPI: widespread pain index; BMI; body mass index; SE: standard error; OR: odds ratio; CI: confidence intervals. 1 Adjusted for age, demographics, body mass index, pain duration. 2 Adjusted for age, demographics, body mass index, pain duration, and widespread pain index. Significance is indicated by ** p < 0.01, *** p < 0.001.
