Statistical significance and p-values were assessed for ordinal variables using Wilcoxon rank sum tests1 and for categorical variables using Chi-squared tests2. GCS = Glasgow coma scale; Temp = temperature (degrees Celcius); SBP = systolic blood pressure (mmHg); DBP = diastolic blood pressure (mmHg); HR = heart rate (beats per minute); RR = respiratory rate (breaths per minute); O2Sat = oxygen saturation (%).
Significant values are in bold.
