Fig. 2From: Improved RIDIT statistic approach provides more intuitive and informative interpretation of EQ-5D dataPower estimated by MWW (Δ) and Improved RIDIT (×) for comparison between two randomly independent samples X (size, nx) and Y (size, ny) simulated from the EQ-5D dimension profiles in Fig. 1a and Fig. 1c, respectively. Simulation was based on 10, 000 replications and a nominal α = 0.05 (two-sided)Back to article page
