When pathological parameters were included, LASSO regression selected twelve variables (pathological type, neuropsychiatric involvement, C3 deposition, CI, renal hypertension, CLR, neutrophils/karyorrhexis, SLEDAI, urine α1-MG, platelet (PLT), BUN, albumin (ALB)) from 215 LN patients at λ=0.06 (minimum mean square error; Figure 5D, 5E). This evidence concerns the gene ALB and renal hypertension.
