Coronavirus disease 2019 (COVID‐19) is associated with adverse outcomes, including need for invasive mechanical ventilation and death in people with risk factors. Liver enzyme elevation is commonly seen in this group, but its clinical significance remains elusive. In this study, we calculated the Fibrosis‐4 (FIB‐4) score for a cohort of hospitalized patients with COVID‐19 and assessed its association with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) RNA, inflammatory cytokine levels, and clinical outcome. A total of 202 hospitalized participants who tested positive for SARS‐CoV‐2 by nasopharyngeal sampling were included in this analysis. FIB‐4 was calculated for each participant using the alanine aminotransferase, aspartate aminotransferase, age, and platelet count. We evaluated the association between FIB‐4 and mortality using both multivariate logistic regression and Cox proportional hazards model. Correlations between FIB‐4 and SARS‐CoV‐2 RNA and cytokine levels were evaluated using the Spearman test. Among the 202 participants, 22 died. The median FIB‐4 in participants who survived and died were 1.91 and 3.98 (P
