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

Fig. 3

Adjusted odds ratios for in-hospital mortality. Reference for potassium categories is > 3.5–4.0 mmol/l, for potassium variability 1st SD. Unadjusted: n = 53,248 patients. Adjusted model 1: n = 30,558 patients, 22,690 missing values adjusted for gender, age and pH value. Adjusted model 2: n = 25,636 patients, 27,612 missing values, adjusted for gender, age, glucose mean, glucose SD, glucose maximum, glucose minimum, sodium mean, sodium SD, APACHE II score, SOFA score maximum, diabetes, acute kidney injury (AKI), chronic kidney disease (CKD), atrial fibrillation, number of measurements, ICU length of stay (in hours) and mean pH value; corrected for missing values by 20-fold imputations. Blood glucose concentrations in mg/dl and sodium concentration in mmol/l. Forest plot of original data from model 2
