Table 2 Optimal cutoff values and transformations for continuous variables
Variable | Optimal Cutoff values | Binary conversion |
|---|---|---|
BUN | 15.3550 mmol/L | If ≤ 15.3550 mmol/L, then n = 1; If > 15.3550 mmol/L, then n = 0 |
CRP | 103.925 mg/L | If > 103.925 mg/L, then n = 1; If ≤ 103.925 mg/L, then n = 0 |
BNP | 589.400 pg/mL | If ≤ 589.400 pg/mL, then n = 1; If > 589.400 pg/mL, then n = 0 |
average RU volume | 375.00 mL | If ≤ 375.00 mL, then n = 1; >375.00 mL, then n = 0 |
UCR | 1.950 | If ≤ 1.950, then n = 1; If > 1.950, then n = 0 |
