Fig. 2From: Usefulness of lactate to albumin ratio for predicting in-hospital mortality in atrial fibrillation patients admitted to the intensive care unit: a retrospective analysis from MIMIC-IV databaseX-tile analyses to obtain the optimal cut-off value of lactate-to-albumin ratio. X-tile plots for patients with critically ill atrial fibrillation are shown on the left panels; the black circles indicate the optimal cut-off values, which are also presented in histograms (middle panels). Kaplan-Meier curves are shown in the right panelsBack to article page
