Table 3.

Subsection a Comparison of pathologists to the 27 pathologists that read > 600 CRPS. Number of outlier pathologists based on the group median diagnostic rate. The number of “ < 2 SD” and “ > 2 SD” pathologists total 27. Subsection b Comparison of pathologists to the 27 pathologists that read > 600 CRPS (normalized). Fraction that are outliers for control charts around the group median diagnostic rate. The numbers in this table are generated by dividing through by the total number of pathologists (27). Subsection c Comparison of pathologists to the hospital site. Number of outlier pathologists based on the group median for the individual hospital sites. Subsection d Comparison of pathologists to the hospital site (normalized). Fraction that are outliers for control charts around the group median diagnostic rate for the each of the hospital sites. The numbers in this table are generated by dividing through by the total number of pathologists (27).
