Table 3 Associations between IPFP area, cartilage volume and cartilage defects

From: Infrapatellar fat pad in the knee: is local fat good or bad for knee osteoarthritis?

  Univariable Multivariable* Multivariable**
Cartilage volume, β (95% CI)    
Medial tibial, ml/cm2 0.27 (0.24, 0.30) 0.09 (0.05, 0.13) 0.06 (0.02, 0.10)

  1. *Adjusted for age, sex, height, weight, tibial bone size, diabetes, cardiovascular diseases, asthma, rheumatoid arthritis, and patellofemoral synovitis. **Further adjusted for radiographic osteoarthritis. Significant differences are shown in bold. ml/cm2, with per-cm2 increase in IPFP area, cartilage volume increases in ml.
