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

Figure 3 Association between the first value of serum lactate dehydrogenase and survival time of patients with critical coronavirus disease 2019. Kaplan-Meier analysis and the log-rank test were performed to analyze the association between the first values of serum lactate dehydrogenase (LDH) and the survival time of patients with critical coronavirus disease 2019. A: Patients with high LDH (≥ 397.0 U/L) had a significantly shorter survival time compared to those with low LDH (< 397.0 U/L) in the alveolitis phase; B: Patients with high LDH (≥ 263.0 U/L) also had a significantly shorter survival time compared to those with low LDH (< 263.0 U/L) in the fibrosis phase. LDH: Lactate dehydrogenase.
