High serum lactate dehydrogenase and dyspnea: Positive predictors of adverse outcome in critical COVID-19 patients in Yichang

Figure 2 The relationship between serum lactate dehydrogenase levels and the prognosis of patients with critical coronavirus disease 2019. The first, lowest and highest values of serum lactate dehydrogenase (LDH), together with the days with high LDH (≥ 397.0 U/L in the alveolitis phase and ≥ 263.0 U/L in the fibrosis phase according to the receiver operating characteristic curve analysis, respectively) and the ratio of the days with high LDH to disease duration were analyzed by the Mann-Whitney U test between non-survivors and survivors in the alveolitis phase and fibrosis phase. P < 0.05 was considered statistically significant. LDH: Lactate dehydrogenase.
