Fig. 5: The ratio between the empirical prediction accuracies in the large- and small-scale designs for three types of traits.

The fifty traits were classified into three types of traits, i.e., mental, physical and lifestyle traits, for the analyses with unrelated individuals (a) and first-degree relatives (b). The main bars represent the mean values of ratios averaged over the analyses of 8, 37 and 5 traits in mental, physical and lifestyle traits, respectively. The error bars show the 95% confidence intervals of the mean ratios. The red horizontal line indicates a ratio of 1.
