Predictive Value of Arterial Blood Lactic Acid Concentration on the Risk of in-Hospital All-Cause Death in Patients with Acute Heart Failure
Figure 2
Restricted cubic spline plots of associations between lactic acid levels and in-hospital all-cause mortality. Note: Analyses were adjusted for age, ethnicity, body mass index, weight, systolic blood pressure, the history of atrial fibrillation, liver cirrhosis, acute myocardial infarction, chronic kidney disease, respiratory failure, chronic obstructive pulmonary disease, ventricular fibrillation, diabetes mellitus, septicaemia, serum anion gap, bicarbonate, blood urea nitrogen, calcium, serum creatinine, glucose, hematocrit, hemoglobin, platelet, red blood cells, C reactive protein, length of stay, albumin, white blood cells, N terminal pro B type natriuretic peptide, cardiotonic drugs, nitroglycerin drugs, furosemide drugs, infection-fighting drugs, simplified Acute Physiology Score II, and sequential organ failure assessment. The solid line and dashed line represent the log-transformed odds ratios and corresponding 95% confidence intervals.
