Statistics of donation frequency (months/times) in pandemic recruitment. The donation frequency characteristics of blood donors recruited were analyzed, donors with donation frequency between 7 and 12 months/times made up the majority of donors who were successfully recruited during the pandemics. (A) Donation frequency of donors in 2020 (ML). (B) Donation frequency of donors in 2020 (RT). (C) Donation frequency of donors in 2021 (Aligned-A). (D) Donation frequency of donors in 2021 (Unaligned-A). (E) Donation frequency of donors in 2021 (RT-A). (F) Donation frequency of donors in 2021 (Aligned-B). (G) Donation frequency of donors in 2021 (Unaligned-B). (H) Donation frequency of donors in 2021 (RT-B). (I) Donation frequency of donors in 2021 (Aligned-O). (J) Donation frequency of donors in 2021 (Unaligned-O). (K) Donation frequency of donors in 2021 (RT-O). (L) Donation frequency of donors in 2021 (Aligned-AB). (M) Donation frequency of donors in 2021 (Unaligned-AB). (N) Donation frequency of donors in 2021 (RT-AB).
