Table 2. Multivariate logistic regression analysis of independent risk factor for renal impairment in systemic lupus erythematosus.

Variables	95% CI	P-value	OR value
Hypercholesterolemia was diagnosed when serum total cholesterol >6.2 mmol/L. Hyperuricemia was diagnosed when serum uric acid >420 μmol/L in men or >360 μmol/L in women.Blood triglyceride levels were greater than 1.7 mmol/L in hypertriglyceridemia. The cut-off value of the proportion of CD4+CD8+ double positive T (DPT) lymphocytes was 1.42%. aMale was used as the reference category for sex. CI: confidence interval; OR: odds ratio.
Hypercholesterolemia	0.505–3.742	0.534	1.375
Hypertriglyceridemia	1.288–5.577	0.013	2.617
Hyperuricemia	1.597–6.757	0.001	3.285
Sexa	0.264–2.065	0.563	0.738
CD4+CD8+ DPT	2.115–12.473	<0.001	5.136
