  1. Reliable rules are defined as those with accuracy greater than 85%. FSBP represents initial blood pressure; ISS stands for Injury Severity Score; EDGCSTOTAL is the total Glasgow Coma Score recorded in the emergency department; EDRTS is the Emergency Department Revised Trauma Score; ARDS stands for Acute Respiratory Distress Syndrome.
