Table 4 ORs for radiographic knee OA progression* OR: odds ratio, CI: confidence interval, BMI: body mass index, IPFP CSA: cross sectional area of infrapatellar fat pad, SCATthigh: subcutaneous fat assessment around distal thigh, Δ: changes over 24 months from baseline, Hoffa synovitis and effusion synovitis were scored based on MOAKS * ORs are derived from separate, multivariable conditional logistic regression models
