Further multivariate logistic regression analysis showed that ALB (OR: 0.965, 95% CI: 0.952–0.978, p = 0.000), sodium supplementation (OR: 3.230, 95% CI: 1.318–7.915, p = 0.010), potassium supplementation (OR: 3.443, 95% CI: 1.643–7.211, p = 0.001), and anti-infection (OR: 3.076, 95% CI: 1.694–5.586, p = 0.000) were all influencing factors for hospitalization expenses (Table 8). Here, ALB is linked to infection.
