The figure shows a comparison of pretreatment DNA methylation heritability estimates from Nustad et al.  and Almeida et al. . Each dot represents a 0.01 × 0.01 square with the color indicating the number of estimates that fall within the square. The red line is the 1-to-1 line, while the dark blue contour lines present the estimated 2-dimensional density. The displayed heritability estimates are those that passed the model selection step in Nustad et al.
