*Excluded variables with subgroups of n ≤ 6 (age, race, insurance type, diabetes).
Multivariate linear regression, R2 = 0.63. Only statistically significant coefficients displayed.
This represents a paired t-test determining significance of the baseline and follow-up PDQ.
This variable had a statistically significant association with a change in PDQ score on univariate analysis using a two-sample t-test, p = 0.02.
