Fig. 2From: Synovial fluid adipokines are associated with clinical severity in knee osteoarthritis: a cross-sectional study in female patients with joint effusionScatterplot of visfatin vs Lequesne index after stratification by resistin levels. Values were corrected for confounders, except for resistin, using the complete model (multivariate model in Table 3). Levels of resistin were defined using tertiles after correction of their values by measurement round using the complete model. PCC Partial correlation coefficient, 95 % CI PCC interval at 95 % confidence, Interact. pv p Value for the interaction between visfatin and resistin according to an F-test derived from the linear modelBack to article page
