Association of ITGB2 rs2070946 with laboratory and clinical data in RA patients. Data are expressed as mean ± SD or box plot for CRP. In the box plot, the box represents the 25–75% percentiles; the line inside the box represents the median and the upper and lower lines representing the 10–90% percentiles. Data were analyzed using ANOVA followed by Tukey’s multiple comparison test for RF, ESR, and DAS28. For CRP data, the non-parametric Kruskal-Wallis test followed by Dunn’s multiple comparison test was used. Statistical significance was set at P < 0.05
