The distribution of the results was examined using the Kolmogorov-Smirnov test and found as a normal statistical distribution for all the measured parameters. All results were expressed as mean ±standard deviation. The pooled t-test was used for the comparison between the patients and control groups and among subdivided groups in the measured parameters. Pearson’s correlation coefficients (r) were calculated to estimate the correlation between parameters. General linear model (GLM) analysis was used to assess the effects of diagnosis while controlling for confounding variables including BMI and age. Receiver operating curve (ROC) analysis was used to study the opportunity of using chemerin, visfatin, and their ratio as a diagnostic tool for RA. The difference between groups is considered statistically different when p < 0.05.
All statistical analysis was performed using SPSS Statistics Version 25 (2017) by IBM, USA.
