Figure 2: Receiver operating characteristic curves for gall bladder ejection fractions measurements at 30-min, 45-min, and 60-min. Area under receiver operating characteristic curve was largest for 30-min (area under curve 0.952; 95% confidence interval = 0.914–0.989) followed by 45-min (area under curve 0.939; 95% confidence interval = 0.892–0.986)
