Differentiation of acute and chronic hepatitis B in IgM anti-HBc positive patients

Table 2 Multivariate analysis for predicting acute hepatitis B

Variables	RR	95%CI	P value
Age (yr)	0.957	0.895-1.023	0.197
Platelet (× 103/μL)	1.001	0.988-1.014	0.934
Total bilirubin (mg/dL)	1.071	0.927-1.237	0.350
ALT (IU/L)	1.001	1.000-1.001	0.055
HBV DNA (log10 IU/mL)	0.323	0.135-0.773	0.011
IgM anti-HBc titer (S/CO)	1.293	1.125-1.486	< 0.001

AHB: Acute hepatitis B; RR: Relative risk; ALT: Alanine aminotransferase; HBV: Hepatitis B virus; IgM anti-HBc: Immunoglobulin M antibody to hepatitis B core antigen; S/CO: Sample/cutoff value.
