  • Packages for the estimation of win difference

    This paper reported both win ratio and win difference (both unmatched). They used Stata as the statistical package. (https://www.nature.com/articles/s41591-025-04132-5, Fractional flow reserve-guided percutaneous coronary intervention versus medical therapy for stable coronary artery disease: long-term results of the FAME 2 trial)

    I was able to estimate the win ratio by the package of -winratiotest-; however, I don't know how to estimate the win difference in Stata. Anybody knows how? Thanks.

    Looks like we have to do it by hand. Thanks to the Delta method.
