Impact of diuretic use and simplified Pulmonary Embolism Severity Index on serum sodium predicting all-cause mortality post-discharge following acute PE.*

*Unless otherwise indicated, data are presented as adjusted hazard ratio (95% confidence interval). Only univariate variables with p2) and serum hemoglobin level on admission (per 1 g/L). Model 2 added diuretic use on presentation. Model 3 was adjusted for the simplified Pulmonary Embolism Severity Index (incorporates age, history of malignancy, cardiac failure or chronic pulmonary disease, heart rate ≥110 beats/minute, systolic blood pressure
