In the multiple logistic regression analysis, adjusted for sex, age, ethnicity, CURB-65 score, albumin levels, eGFR, diabetes, heart failure, and cerebrovascular disease, hypophosphatemia (Grade 2) (OR = 3.248, 95% CI: 1.238–8.523, p = 0.017) and hyperphosphatemia (OR = 3.184, 95% CI: 1.970–5.146, p < 0.001) were identified as independent correlative factors of mechanical ventilation (Table 3). This evidence concerns the gene ALB and heart failure.
