Table 3 30-day mortality per triage group, logistic regression analysis results. Model A (gender, age), model B (Model A and LOS, cause of contact, and prehospital care), model C (Model B and in-hospital care) . Odds Ratios (OR) compared to age group 18–59 years. ***: p < 0.001

From: Age is associated with increased mortality in the RETTS-A triage scale
