AOR with 95% confidence intervals that include 1.0 are not statistically significant. Gender was retained in the model for Improved Pain due to the presence of the interaction term, M1 pain score × female gender.
GDS = Geriatric Depression Scale; AOR = adjusted odds ratios; OR = odds ratios.
All ORs are adjusted for all other variables in the model. Unless noted, the final models were limited to variables with statistically significant AORs.
