The number of available CAD regions was 587. Table 4 shows that on average 274.2 of the 546 false-positive CAD regions (50.2%) were not queried. It also shows that on average 5 of the 41 true-positive CAD regions (12.2%) were not queried. The radiologists queried far fewer false-positive CAD regions than the non-radiologists.\nTable 4 Number of CAD regions queried\nQueried CAD regions Non-queried FP CAD regions Non-queried, unreported TP CAD regions Non-queried CAD regions but reported TP finding\nNon-radiologists\n1 290 293 2 2\n2 338 244 3 2\n3 330 251 4 2\n4 500 83 3 1\n5 196 377 7 7\nAverage 330.8 249.6 3.8 2.8\nRadiologists\n6 176 396 8 7\n7 262 319 6 0\n8 209 365 9 4\n9 444 140 3 0\nAverage 272.75 305 6.5 2.75\nReader average 305 274.22 5 2.78\nThere were 587 CAD regions in total; 546 false-positive CAD regions and 41 true-positive CAD regions","divisions":[{"label":"label","span":{"begin":474,"end":481}},{"label":"caption","span":{"begin":482,"end":511}},{"label":"p","span":{"begin":482,"end":511}},{"label":"table","span":{"begin":512,"end":889}},{"label":"tr","span":{"begin":512,"end":645}},{"label":"th","span":{"begin":512,"end":531}},{"label":"th","span":{"begin":532,"end":558}},{"label":"th","span":{"begin":559,"end":597}},{"label":"th","span":{"begin":598,"end":645}},{"label":"tr","span":{"begin":646,"end":662}},{"label":"td","span":{"begin":646,"end":662}},{"label":"tr","span":{"begin":663,"end":676}},{"label":"td","span":{"begin":663,"end":665}},{"label":"td","span":{"begin":665,"end":668}},{"label":"td","span":{"begin":669,"end":672}},{"label":"td","span":{"begin":673,"end":674}},{"label":"td","span":{"begin":675,"end":676}},{"label":"tr","span":{"begin":677,"end":690}},{"label":"td","span":{"begin":677,"end":679}},{"label":"td","span":{"begin":679,"end":682}},{"label":"td","span":{"begin":683,"end":686}},{"label":"td","span":{"begin":687,"end":688}},{"label":"td","span":{"begin":689,"end":690}},{"label":"tr","span":{"begin":691,"end":704}},{"label":"td","span":{"begin":691,"end":693}},{"label":"td","span":{"begin":693,"end":696}},{"label":"td","span":{"begin":697,"end":700}},{"label":"td","span":{"begin":701,"end":702}},{"label":"td","span":{"begin":703,"end":704}},{"label":"tr","span":{"begin":705,"end":717}},{"label":"td","span":{"begin":705,"end":707}},{"label":"td","span":{"begin":707,"end":710}},{"label":"td","span":{"begin":711,"end":713}},{"label":"td","span":{"begin":714,"end":715}},{"label":"td","span":{"begin":716,"end":717}},{"label":"tr","span":{"begin":718,"end":731}},{"label":"td","span":{"begin":718,"end":720}},{"label":"td","span":{"begin":720,"end":723}},{"label":"td","span":{"begin":724,"end":727}},{"label":"td","span":{"begin":728,"end":729}},{"label":"td","span":{"begin":730,"end":731}},{"label":"tr","span":{"begin":732,"end":759}},{"label":"td","span":{"begin":732,"end":740}},{"label":"td","span":{"begin":740,"end":745}},{"label":"td","span":{"begin":746,"end":751}},{"label":"td","span":{"begin":752,"end":755}},{"label":"td","span":{"begin":756,"end":759}},{"label":"tr","span":{"begin":760,"end":772}},{"label":"td","span":{"begin":760,"end":772}},{"label":"tr","span":{"begin":773,"end":786}},{"label":"td","span":{"begin":773,"end":775}},{"label":"td","span":{"begin":775,"end":778}},{"label":"td","span":{"begin":779,"end":782}},{"label":"td","span":{"begin":783,"end":784}},{"label":"td","span":{"begin":785,"end":786}},{"label":"tr","span":{"begin":787,"end":800}},{"label":"td","span":{"begin":787,"end":789}},{"label":"td","span":{"begin":789,"end":792}},{"label":"td","span":{"begin":793,"end":796}},{"label":"td","span":{"begin":797,"end":798}},{"label":"td","span":{"begin":799,"end":800}},{"label":"tr","span":{"begin":801,"end":814}},{"label":"td","span":{"begin":801,"end":803}},{"label":"td","span":{"begin":803,"end":806}},{"label":"td","span":{"begin":807,"end":810}},{"label":"td","span":{"begin":811,"end":812}},{"label":"td","span":{"begin":813,"end":814}},{"label":"tr","span":{"begin":815,"end":828}},{"label":"td","span":{"begin":815,"end":817}},{"label":"td","span":{"begin":817,"end":820}},{"label":"td","span":{"begin":821,"end":824}},{"label":"td","span":{"begin":825,"end":826}},{"label":"td","span":{"begin":827,"end":828}},{"label":"tr","span":{"begin":829,"end":856}},{"label":"td","span":{"begin":829,"end":837}},{"label":"td","span":{"begin":837,"end":843}},{"label":"td","span":{"begin":844,"end":847}},{"label":"td","span":{"begin":848,"end":851}},{"label":"td","span":{"begin":852,"end":856}},{"label":"tr","span":{"begin":857,"end":889}},{"label":"td","span":{"begin":857,"end":872}},{"label":"td","span":{"begin":872,"end":875}},{"label":"td","span":{"begin":876,"end":882}},{"label":"td","span":{"begin":883,"end":884}},{"label":"td","span":{"begin":885,"end":889}}],"tracks":[]}
