Relationship between serum bilirubin concentrations and diabetic nephropathy in Shanghai Han’s patients with type 1 diabetes mellitus

Table 5 Prevalence of DN in patients with T1DM according to quartiles of serum bilirubin concentrations

Bilirubin quartile	Prevalence (%)	Unadjusted		Adjusted
Bilirubin quartile	Prevalence (%)	OR (95% CI)	P-value	OR (95% CI)	P-value
Q1 (n = 64)	21.90	1 (Referent)
Q2 (n = 76)	17.10	0.74 (0.32–1.71)	0.48	0.52 (0.19–1.41)	0.20
Q3 (n = 68)	7.40	0.28 (0.10–0.84)	0.02*	0.24 (0.07–0.82)	0.04*
Q4 (n = 50)	2.00	0.07 (0.01–0.58)	0.01*	0.11 (0.01–0.92)	0.02*
P trend for ORs			0.02*		0.04*

Adjustment based on duration of diabetes, BMI, TG, Albumin, Haemoglobin and WHR
