    Snippet: A total of 1,588 cases without COVID-19 were included as references for propensity score matching. After achieving a balanced cohort through propensity score matching, 89 patients with COVID-19 (the COVID-19 group) and 173 patients without COVID-19 (the Control group) were obtained. Among them, 5 patients with COVID-19 successfully matched only one counterpart because of the strict matching conditions and others successfully matched two counterpa.....
    Document: A total of 1,588 cases without COVID-19 were included as references for propensity score matching. After achieving a balanced cohort through propensity score matching, 89 patients with COVID-19 (the COVID-19 group) and 173 patients without COVID-19 (the Control group) were obtained. Among them, 5 patients with COVID-19 successfully matched only one counterpart because of the strict matching conditions and others successfully matched two counterparts. A flowchart was shown in Figure 2 . The distributions of patient characteristics before and after propensity score matching are shown in Table 2 . After, propensity score matching, the baseline characteristics between the two groups were comparable (all p>0.05).
