Effect of delaying cryopreservation on post-thaw CD45⁺and CD34⁺cell viabilities and CD34⁺cell recovery. Data pertaining to apheresis cryopreserved the same day of the collection (grey, d0) are compared to apheresis cryopreserved after overnight storage at + 4–10 °C (white, d1). Data is presented as box and whiskers, representing median with interquartile range, with whiskers representing min and max values, and outliers as dots. Variables compared are CD45⁺ viability, CD34⁺ cell viability and CD34⁺ cell recovery (compared to pre-cryopreservation). p values are reported above the groups using Mann–Whitney test for null hypothesis testing
