  1. Dependent variable: joint space narrowing (JSN) or osteophyte score. Independent variable: subgastrocnemius bursitis or popliteal cyst, per grade. *Adjusted for age, sex, body mass index, disease status, medial or lateral tibiofemoral osteophytes for JSN, or medial or lateral tibiofemoral JSN for osteophytes. Data in bold denote statistically significant results.
