Fig. 1. Concentrations of PDX in active- and inactive-RA patients and in HCs.
A Levels of PDX in serum samples from HCs (n = 34), patients with inactive RA (n = 34), and patients with active RA (n = 34; F[3,102] = 22.97). B Correlation between serum PDX level and DAS28 score (n = 54). C ROC curve analysis was performed to analyze the diagnostic value of serum PDX expression levels in active RA. Data were presented as means ± SD. Differences among the three groups were assessed by one-way ANOVA, and post hoc tests (Tukey’s method) were applied to investigate the differences one by one.
