Analysis Independent variables B (95% CI) β p Semi-partial r2× 100%
1. BMI 0.07 (0.03, 0.12) 0.19 0.002 3.5%
2. HADS depression 0.12 (0.04, 0.20) 0.17 0.005 2.9%
3. BMI 0.06 (0.02, 0.11) 0.16 0.009 2.4%
HADS depression 0.09 (0.01, 0.18) 0.14 0.025 1.8%
Dominance analysis
Overall average BMI (0.035 + 0.024)/2 = 0.030 3.0%
Overall average HADS depression (0.029 + 0.018)/2 = 0.023 2.3%

Knee pain was measured with a numeric rating scale for knee pain during the last week. In all analyses we adjusted for age, gender, marital status, education level, radiographic OA and comorbidity. B (95% CI), regression coefficient ( 95% confidence interval). β, Standardized regression coefficient. Semi-partial r2, Squared semi-partial correlation coefficient. BMI, Body-mass index. HADS, Hospital Anxiety and Depression Scale.
