Statistics of donor’s age (years) in pandemic recruitment. The age characteristics of blood donors recruited were analyzed, donors with more than 40 years old made up the majority of donors successfully recruited during the pandemics. (A) Ages of donors in 2020 (ML). (B) Ages of donors in 2020 (RT). (C) Ages of donors in 2021 (Aligned-A). (D) Ages of donors in 2021 (Unaligned-A). (E) Ages of donors in 2021 (RT-A). (F) Ages of donors in 2021 (Aligned-B). (G) Ages of donors in 2021 (Unaligned-B). (H) Ages of donors in 2021 (RT-B). (I) Ages of donors in 2021 (Aligned-O). (J) Ages of donors in 2021 (Unaligned-O). (K) Ages of donors in 2021 (RT-O). (L) Ages of donors in 2021 (Aligned-AB). (M) Ages of donors in 2021 (Unaligned-AB). (N) Ages of donors in 2021 (RT-AB).
