Results of the multivariate regression analysis of the association between death and several demographic and medical history factors including presenting with abdominal pain, nausea, vomiting or diarrhea (ANVD).

Predictor	Odds ratio of death	95% Confidence Interval	P-value
African American	−0.31	−1.45 to 0.73	0.57
Latinx	−0.55	−1.78 to 0.64	0.36
White	0.78	−0.71 to 2.32	0.3
Age	-0.04	-0.07 to -0.02	0.0002
Body Mass Index (BMI)	-0.04	-0.08 to -0.007	0.02
Sex	-1.08	-1.69 to -0.49	0.0004
Acute Renal Failure (ARF)	1.63	0.99 to 2.33	0.000002
AIDS	1.73	−011 to 4.72	0.12
ANVD	0.75	0.16 to 1.37	0.014
Chronic Pulmonary Disease	−0.28	−0.91 to 0.36	0.38
Congestive Heart Failure	−0.19	−0.89 to 0.54	0.61
Diabetes	0.16	−0.45 to 0.77	0.61
Hemodialysis on Admission	0.58	−1.91 to 3.81	0.67
Hypertension	0.36	−0.4 to 1.11	0.35
Venous Thromboembolism	0.61	−0.58 to 2.01	0.34

The protective effect of ANVD was replicated in this multivariate logistic regression to control for any possible confounders. Other highlighted features were expectedly associated with the outcome as well (Age, BMI and ARF on presenation).
