Fig. 4
Scatterplots and linear correlation between Novocure and physician magnetic resonance imaging (MRI) measurement for MRI cases 1 to 5. Error bars represent ±7.5 mm from Novocure measurements. Each color represents a set of measurements made by a different physician (n = 14). Mean (SD) R 2 linear correlations for all physicians versus Novocure were a case 1, 0.9966 (0.0039); b case 2, 0.9954 (0.0041); c case 3, 0.9967 (0.0050); d case 4, 0.9963 (0.0037); and e case 5, 0.9935 (0.0066)
