Prevalence of NAb positivity in adult participants by AAV serotype and country at 1:1 and 1:4 serum dilutions

Heatmaps show the prevalence of NAb activity against six AAV serotypes for all adult participants (left column; n = 502) and the subset of participants from each country for the (A) 1:1 and (B) 1:4 serum dilutions. Numbers inside squares indicate the percentage of serum samples positive for NAb activity against the designated serotype in the designated country (out of all samples tested for that AAV in that country). AAV, adeno-associated virus; Nab, neutralizing antibody; USA, United States; CAN, Canada; UK, United Kingdom; DEU, Germany; ESP, Spain; ITA, Italy; FRA, France; AUS, Australia; JPN, Japan; KOR, South Korea.
