Taken together, the higher heritability, the greater magnitude of the heritability z-score (indicative of a stronger polygenic signal), and the larger rg with other health-related traits confirm that PCL-Total is similar to, but more informative than, the case-control definition (for either MVP alone or the MVP/PGC meta-analysis). Accordingly, all subsequent post-GWAS analyses are based on the more powerful PCL-Total quantitative trait dataset in the EUR sample.
