  1. Footnote: Functional status is measured on four COOP-WONCA scales: physical fitness, feelings, daily activities, social activities, and the dependent variable in all analyses is sum score of these charts. ΔR2: the change in R2 (multiple correlation coefficient) accounted for by the variable; β: unstandardised regression coefficient; CI: Confidence interval; St.β:Standardised β value. Model A: Linear regression analysis performed with individual symptoms, controlling for age and sex. Model B: Multiple regression model controlling for all other symptoms, in addition to age and sex.
