Fig. 1

In-hospital outcomes for AKI versus non-AKI patients. Notes: This figure shows a comparison of in-hospital mortality, 30-day mortality, ICU admission, mechanical ventilation, invasive mechanical ventilation, and non-invasive mechanical ventilation between AKI and the non-AKI patients. The numbers at the top of the individual bars reflect the percentages of each outcome within this group. P-values were calculated using Pearson chi-squared/Fisher’s exact tests where appropriate. Abbreviations: AKI, acute kidney injury; ICU, intensive care unit
