  1. Abbreviations: WORMS Whole-Organ Magnetic Resonance Imaging Score, BML bone marrow lesion, JSN joint space narrowing, FDR false discovery rate. JSN values are expressed in mm as mean ± standard deviation (SD). All comparisons are versus non-progressors (JSN ≤ 0 mm). Significant p values are represented in bold font
