From: Diagnostic errors in the new millennium: a follow-up autopsy study
Changes in discrepancy classes I–VI over the study years. Class I decreased from 16 to 2% (P<0.001) and class II decreased from 14 to 5% (P=0.026). Major diagnostic errors (class I and II) decreased from 30 to 7% (P<0.001). Class III increased from 13 to 16% (P=0.207) and class IV from 10 to 37% (P<0.001). Minor diagnostic errors increased from 23 to 53% (P<0.001). Class V decreased from 43 to 35% (P=0.212) and class VI from 4 to 5% (P=1.000).
