The table displays age, gender, ASA classification performed by attending anesthesiologist during preoperative evaluation, distribution of comorbidities (Columns do not sum up to 100% as a patient may have one or more comorbidities), complete blood count values (including hemoglobin, hematocrit, platelet count, and white blood cell count), and type of emergency surgery. Totals and differences between survivors and deceased are described. P value <0.05 is considered significant
