2. Fig 1
Risk prediction score validation. The estimated risk of developing a respiratory adverse event (RAE) for each point total (x-axis) compared with the actual incidence of RAE for that same point total (y-axis) of the remaining 15% of cohort. Each circle represents a point total and the color represents the risk group of each point total. An x = y reference line was drawn to demonstrate correlation. The most extreme 0.5% of patients (point total >26) were excluded.
