Fig. 3 — Leaf plots displaying the relationship between the assumed pre-test probability (on the x-axis) and the post-test probability (on the y-axis) of acute kidney injury (AKI) for the following cut-off: a severe congestion (Grade 3) defined by the VExUS C grading system and b central venous pressure of ≥ 12 mmHg. The upper half part of the curve indicates the post-test probability in case of a positive result while the lower half indicated is for a negative test result. The dashed double-sided arrow indicated the test performance considering the incidence of acute kidney injury (pre-rest probability) within the studied cohort (33.8%)
