ALB and primary biliary cholangitis: Multivariable logistic regression analysis identified that serum ANA(≥1:1000) (OR= 2.180, 95% CI: 1.261–3.769), elevated GGT (OR = 1.002, 95% CI: 1.001–1.003, P= 0.001) and TBIL (OR= 1.020, 95% CI: 1.005–1.035), lowed ALB (OR= 0.943, 95% CI: 0.896–0.993) as biomarkers for ductopenia in patients with early-stage PBC.
