Fig. 1From: RETRACTED ARTICLE: Does serum B lymphocyte chemoattractant protein13 (CXCL13) level correlate with parameters of disease activity and severity in rheumatoid arthritis? Clinical and musculoskeletal ultrasonographic assessmentComparison between the RA patients and controls regarding the mean serum CXCL13 levels. This figure showed that the mean CXCL13 value was significantly higher in the RA patients (388.86 ± 283.63 pg/ml), than in the controls (62.96 ± 32.5 pg/ml) (P < 0.001). Cut-off level of CXCL13 is 111 pg/ml. CXCL13 serum B lymphocyte chemoattractant protein13, P < 0.001** highly significantBack to article page
