Adjusted hazard ratios (HRs) of knee pain according to depressive symptoms scores. Notes: Graphs show HRs for incident knee pain (Panel A) and persistent knee pain (Panel B). HRs were adjusted for demographic characteristics, socioeconomic status (SES), health status, and health-related behavior. Data were fitted by a 3-knots restricted cubic spline Cox proportional hazards regression model. The depressive symptoms score ranges from 0 to 30, with the highest score representing the highest risk of depressive symptoms. Solid lines indicate HRs, and dashed lines indicate 95% CIs
