  1. All variables were tested with the Kolmogorov-Smirnov normality test. Pearson correlation was used when the variables were normally distributed; otherwise, Spearman correlation was used. Only significant variables are shown. ap < 0.001; bp < 0.01; cp < 0.05. BMD, bone mineral density; ICTP, C-terminal telopeptide of type I collagen; IgG, immunoglobulin G; r, Pearson correlation coefficient; rs, Spearman correlation coefficient; sIL-6R, soluble interleukin-6 receptor; SLE, systemic lupus erythematosus.
