Figure 2. Postoperative outcomes of all patients with acute abdomen. Data are presented as numbers and percentages for categorical variables, and continuous data are expressed as the mean ± standard deviation (SD). *P< 0.05, **P< 0.01, ***P <0.001, based on Student’s t-test. (A) the difference between both groups in clinical outcomes; (BM) shows the differences between patients with and without COVID-19 pneumonia in postoperative laboratory findings, including (B) WBCs (white blood cells); (C) neutrophils; (D) lymphocytes; (E) HGB (hemoglobin); (F) CRP (C-reactive protein); (G) PCT (procalcitonin); (H) Albumin; (I) ALT (alanine aminotransferase); (J) AST (aspartate aminotransferase); (K) D-dimer; (L) APTT (activated partial thromboplastin time); (M) PT (prothrombin time). Red and blue marks represent patients with and without COVID-19 pneumonia, respectively.
