Superimposed Kaplan-Meier curves comparing the probability of difference between the manual reading 1 vs. manual reading 2 (in black), the mean of manual readings vs. old macro (in red) and mean of manual readings vs. new procedure (in green). The X axis represents count differences between the two methods or readings compared and the Y axis represents the probability of observing these differences. The upper row (A) represents the results obtained with DIs grouped in function of the background level: DIs with background (A1) versus DIs without background (A2). The lower row represents the results obtained with DIs grouped in function of their complexity: high-complexity DIs (B1) and low-complexity DIs (B2).
