Summary of the findings.
Fig 1.
The top row (a0-d0) shows the raw PIRs in bar charts for the components of the Nottingham grade (tubular score (TS), nuclear score (NS), mitotic score (MS)) and the Nottingham grade.
Green is score 1, yellow is score 2 and red is score 3. The control charts (a1-d3) show the normed PIRs for the components of the Nottingham grade (TSx, NSx, MSx) and the Nottingham grade (Gx). The bars (in the bar chart) and red circles (in the control charts) represent individual pathologists which are ordered randomly. Pathologists in the bar charts (e.g. pathologist #1) correspond to pathologists in the control charts. The black line in the centre of the control chart is the group median interpretative rate (GMIR). The dashed blue (control) lines on either side of the GMIR represent the boundaries of the 95% confidence interval (CI) and correspond to p = 0.05. The solid blue (control) lines represent the boundaries of the 99.9% CI and correspond to p = 0.001. The dashed blue (control) lines beyond the solid blue lines represent p = 1e-6 and p = 1e-12 respectively.
