Table 3. Agreement between AGST score and TN CTAS score: overall, by age, sex, and triage category.
*P-values for comparison of agreement categories: age, continuous = 0.43 (ANOVA); age, categorical = 0.53; †p-values for comparison of agreement between sexes = 0.04
AGST: algorithm-generated self-triage score; TN: triage nurse; CTAS: Canadian Triage and Acuity Scale; ANOVA: analysis of variance
