All-cause mortality and serum sodium fluctuation post acute PE.^*

*Unless otherwise indicated, data are presented as adjusted hazard ratio (95% confidence interval). Only univariate variables with p<0.10 were included in the multivariate analysis. Multivariate logistic regression analysis was performed for in-hospital death, whilst multivariate Cox proportional hazards regression was performed for post-discharge death analysis. For in-hospital death, the multivariate model was adjusted for age (per 1-year), Charlson Comorbidity Index score (per 1-score) and serum hemoglobin level (per 1 g/L). Diuretic use on presentation was not a univariate predictor of in-hospital death. For post-discharge death, the multivariate model was adjusted for age, Charlson Comorbidity Index score, whether patient had atrial fibrillation and/or flutter, current smoker status, diuretic use on presentation, the estimated glomerular filtration rate (per 1 ml/min/1.73 m2) and serum hemoglobin level on admission. †There were no in-hospital deaths in Group 3 patients.
