Compared to the control group, the C3 and C4 levels were lower significantly in both the LN and non-LN groups (p < 0.001) Nevertheless, no statistically significant variations were observed in the levels of ESR, anti-dsDNA, C3, C4, or LAC among the LN and non-LN groups (Table 1). This evidence concerns the gene LCT and lobular neoplasia.
