Hmm, I get 2x38 for 90% power of a two-sided test at level 10%. But nevermind. I came here to advertize an app which calculates the gain in power if you don't dichotomize. In this case, they would have needed only 2x19. The app is here: vanzwet.shinyapps.io/info_loss/

It has been claimed that there is no such thing as a validated prediction model. We provide empirical evidence for that claim in our new paper here: onlinelibrary.wiley.com/doi/full/10....
