NPPB and chronic kidney disease: We found that six parameters were significantly associated with poor short-term outcomes: low systolic blood pressure (SBP < 90 mmHg); increasing white blood cell (WBC > 9.2 × 109/L); low hematocrit (HCT ≤ 0.407); abnormal liver function (TBIL > 34.2 μmol/L); NT-proBNP ≥ 10728.9 ng/ml and stage 5 CKD (eGFR < 15 ml/min/1.73 m2).
