Absolute and relative frequency of reported reasons not to enroll in the AMYPAD-PNHS. Colored bars: the absolute number of times a reason is reported (% relative to the total number of subjects, n = 477). Gray bars: the remaining subjects that did not report this reason, truncated at 50% for visualization purposes (100% = the total number of 477 subjects). Each subject could provide ≥ 1 reason(s) supporting their refusal and may therefore be assigned to multiple main categories and/or to multiple sub-categories within a main category. A total of 509 main categories and 536 sub-categories have been reported
