Figure 2.

Risk factors of AKI in those with and without COVID-19. Box plots (median, IQR, and whiskers denoting 5^th and 95^th percentiles) or proportion shown. In patients with COVID-19, all variables are missing < 10% except C-reactive protein (26%). In patients without COVID-19, all variables are missing < 10% except D-dimer (86%), ferritin (86%), and C-reactive protein (85%). All variables are reported as maximum before AKI onset except systolic blood pressure, which is reported as minimum.

Abbreviations: ACEI/ARB, angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker; AKI, acute kidney injury; COVID-19, coronavirus disease 2019; SBP, systolic blood pressure.
