AKI, acute kidney injury; ECMO, extracorporeal mechanical oxygenation;
RRT, renal replacement therapy; VV, veno-venous
1Chest drainage volume data were right-skewed and were
ln-transformed. The BTT vs. non-BTT difference is geometric means ratio
(GMR)= exp[mean ln(BTT) – mean ln(non-BTT)]
2Lowest unmeasured confounder effect (on the relative
risk scale) needed to shift the (Bayesian) point estimate (first value)
or the lower limit of the 95% CrI to 1.0 (second value).
