Frequency counts and relative (%) distribution of each grade in expert scoring. The p-values of GT vs. DL were calculated using Mann-Whitney U-test (* significance level < 0.05)Over the testing GTV contours, the cases accepted with no revision account for 80.7% in GT and 69.7% in DL, and those requiring minor revision account for 19.3% in GT and 29.8% in DL. In other words, 100% GT contours and 99.5% DL contours are deemed as clinically viable (Score ≥ 2). Besides, only one GTV-DL case requires major revision. The
