  1. Proportional hazard regression models (Cox) with VExUS grading systems considered as time varying covariates (i.e., VExUS grade at day 0 is used to predict acute kidney injury (AKI) at day 1, VExUS grade at day 1 is used for AKI at day 2 and so on). HR hazard ratio, CI 95% confidence intervals)
