In the multiple logistic regression analysis, adjusted for sex, age, ethnicity, CURB-65 score, albumin levels, eGFR, diabetes, heart failure, and cerebrovascular disease, Grade 1 hypophosphatemia (OR = 2.381, 95% CI: 1.225–4.628, p = 0.011), Grade 2 hypophosphatemia (OR = 9.164, 95% CI: 2.844–29.527, p < 0.001), and hyperphosphatemia (OR = 4.204, 95% CI: 2.169–8.146, p < 0.001) were identified as independent correlative factors of septic shock (Table 4). Here, ALB is linked to hypophosphatemia.
