Table 6.

Comparison of Average Precision (AP) scores. Proportion of Cases in which AP for Row Method was Greater than Column Method t+ indicates a significantly greater row mean than column mean by paired t test w+ indicates a significantly greater row median than column median by Wilcoxon’s signed rank test. Boldface indicates a greater proportion of row cases than column cases had greater AP.
