Evolution of AKI deterioration. a Kaplan Meier representation of first and max detected AKI over time both for any stage (a) and with respect to each individual stage (a.1–3). Here, max AKI does not refer to a specific day, but to the entire ICU time window of 14 days. For clarity, the x and y labels of the subfigures have been removed but can be taken from the main plot. b Sankey plot of max AKI evolution within first three days. Each bin represents the proportion of patients developing no (gray), 1 (green), 2 (blue) or 3 (red) as max AKI stage up to a specific day on ICU after admission. For clarity, bin values less than 1% have been removed
