Table 3 Predictors for sustained virologic response in treatment-naïve hepatitis C virus genotype 1 patients with pegylated interferon α and ribavirin combination therapy

	Odds ratio	95% CI	P value
Vitamin D treatment (Yes vs No)	2.5	2.0-4.9	< 0.001
Baseline vitamin D (< 20 or > 20 IU/mL)	1.5	1.2-3.8	0.080
Advanced fibrosis (< F2 or > F2)	2.0	1.0-3.6	0.001
High viral load (< 800  000 or > 800  000 IU/mL)	2.8	1.2-4.0	0.001
Baseline CRP (< 0.05 or > 0.5 mg/dL)	1.0	0.5-1.9	0.510
Changes in homeostasis model assessment (%)	1.8	0.5-3.0	0.030

CRP: C-reactive protein; CI: Confidence interval.
