MOESM1 of Association between potassium concentrations, variability and supplementation, and in-hospital mortality in ICU patients: a retrospective analysis

Additional file 1: Table S1. Baseline characteristics in categories of potassium variability. Figure S1. Mean potassium groups and in-hospital mortality using smaller cut points. Figure S2. Association between mean potassium levels and in-hospital mortality in patients with atrial fibrillation. Figure S3. Association of mean potassium levels and in-hospital mortality in patients receiving dialysis. Figure S4. First potassium value and in-hospital mortality. Figure S5. Potassium variability (SD) and in-hospital mortality using smaller cut points. Figure S6. Potassium variability shown in groups of coefficient of variation (CV). Figure S7. Combination of mean potassium concentrations and a variability determined in coefficient of variation. Figure S8. Adjusted odds ratios for in-hospital mortality (without pH value). Table S2. Regression in groups of pH value < 7.36, 7.36–7.44, > 7.44 (age, sex). Table S3. Regression in groups of pH value < 7.36, 7.36–7.44, > 7.44 (multiple confounders). Table S4. Mean potassium levels and variability in patients receiving potassium supplementation.
