The results showed that serum apoA-I levels was much higher in female MS patients (1.523 ± 0.082 g/L) and female RA patients (1.120 ± 0.042 g/L) than the corresponding male MS patients (1.262 ± 0.087 g/L; P = 120.033) and male RA patients (0.948 ± 0.049 g/L; P = 120.012) (Figure 3). This evidence concerns the gene APOA1 and rheumatoid arthritis.
