The 95% confidence intervals (95% CIs) obtained for the limits of criteria of stable disease, progressive disease (PD), and partial response (PR) using area. In liver, the 95% CI of area systematically overlapped across all tumour sizes for both partial response and progressive disease. a The 95% CI of the stable disease (y = x) in the lung did not cross the calculated 95% CI of the lower bound of PD (y = 1.44 x). b The 95% CI of the stable disease in the lung did not cross the calculated 95% CI of the upper bound of PR (y = 0.47 x). c The 95% CI of the stable disease in liver systematically shows an overlap (blue zone) with the 95% CI of the lower bound of PD. d The 95% CI of the stable disease in the liver always crossed the calculated 95% CI of the upper bound of PR (blue zone)
