Table 5. Comparative analysis of the age, APACHE II, SIDa, SIDe, and SIG values of the surgical and medical patients based on the status at the time of discharge.

SD, standard deviation; SIG, strong ion gap; SIDa, strong ion difference apparent; SIDe, strong ion difference effective; APACHE, Acute Physiologic Assessment and Chronic Health Evaluation
