Seems that 17% is from 2008-2015 data (this is the link from the original article linked in the post) https://www.amjtransplant.org/article/S1600-6135(22)09789-1/fulltext https://www.amjtransplant.org/article/S1600-6135(22)09789-1/... Also it mentions a policy of relying on SSA data, which makes more sense than checking on each patient manually every 3 months (though the data access got worse due to a policy change). Curious why this doesn't match ther personal experience of the commenter's spouse, should be a high enough number to be noticeable?
