* OR (95% CI): odds ratios with 95% confidence intervals estimated by multiple logistic regression adjusting for age and sex. Each social support domain is modelled separately. The ORs estimate the multiplicative increase in the odds of a MCID decline in PCS per 20-point increase in the social support score. An OR < 1 indicates a protective effect of social support. ORs statistically significant at are in bold font.
The sex interaction is the female-specific OR divided by the male-specific OR. An interaction OR > 1 indicates a greater protective effect of social support for males than females.
