The retrospective studies that have been done, on which the estimates have extrapolated from, have only included the adult population.
Sorry, I'm still confused
The "Dr. Osamu Muramoto" number is extrapolated using the "American Association of Blood Banks reported that approximately 4 million patients" line - where is the indication that the "patients" here only includes adults?
The "Marvin Shilmer" number is extrapolated using the "the average number of publishers during the 2016 service year was 8,132,358" line - where is the indication that the "publishers" here only includes adults?
