ALB and Thrombocytopenia: Stepwise multiple logistic regression analyses identified independent factors significantly associated with thrombocytopenia risk in HBsAg positive subjects, including lower ALB, higher TBIL, higher ALT, and higher ALP, with corresponding ORs (95% CI) of 6.51 (1.32-34.83), 3.71 (1.85-7.24), 1.95 (1.21-3.10), and 6.60 (1.77-26.99), respectively, as shown in Table 3; Supplementary Figure S2.
