Correlation between report accuracy and subjective confidence in report. A first packet attempted (timepoint 1); n = 266*; mean reporting accuracy 66%; mean confidence in report 24%; line of best fit y = 0.4117x-3.0899; rs = 0.394; p-value < 0.00001. B second packet attempted (timepoint 2); n = 259*; mean reporting accuracy 73%; mean confidence in report 31%; line of best fit y = 0.4558x-2.4703; rs = 0.339; p-value < 0.00001. C third packet attempted (timepoint 5); n = 268*; mean reporting accuracy 77%; mean confidence in report 43%; line of best fit y = 0.5918x-2.1069; rs = 0.392; p-value < 0.00001. D fourth packet attempted (timepoint 6); n = 266*; mean reporting accuracy 78%; mean confidence in report 46%; line of best fit y = 0.5105x + 6.0985; rs = 0.321; p-value < 0.00001. *1080 echocardiograms reported, but subjective confidence only rated for 1059 echocardiograms (98.1%)
