GPT and clostridium difficile infection: Comparing the mean results, we have a significant statistical difference between the two groups (CDI + COVID-19 group and CDI group) regarding Carmeli score (p < 0.01), leukocyte count both at admission and at discharge (p = 0.01, p = 0.04), neutrophil count at admission and at discharge (p = 0.03, p = 0.01), creatinine level (p = 0.001), ALT (p = 0.05), LDH (p = 0.025), and platelet count (p < 0.01).
