P-values represent a statistical comparison of the equivalence of means for each day of reporting (means on days 1–4) for each reporter. P-values >0.05 indicate no statistical difference between means across days. ICC Intraclass correlation, Corr Pearson correlation, Dev Difference (observation – staff report)
