Graft ages. (A) Overall age of product (defined as time in hours from collection to end of processing) varied between fresh (red) and cryopreserved (blue) cohorts. Products in the cryopreserved group were more likely to be ≥48 hours old at end of processing, reflecting longer intervals at all stages: transit, holding, and processing times. Of cryopreserved products, 16.8% was >60 hours old at the end of processing compared with 2% of fresh products (P < .0001). (B) International products (blue) tended to be older than domestic products (red). This difference in length of transit time is particularly pronounced in the cryopreserved group, reflective of changes in transit time during the COVID-19 pandemic. Cryo, cryopreserved.
