AKI prevalence at emergency department calculated with multiple baseline definitions and markers (serum creatinine and eGFR). For each baseline time window a surrogate marker was selected from the specified baseline time window with one of the four baseline values. Depending on the availability of measurements, emergency department visits were filtered in each baseline time window described as cutoff. Panel A shows the relative increase of ≥1.5 serum creatinine criterion to baseline and panel B shows relative decrease of < 25% in eGFR
