NPR and PR platelet counts decrease with transport between facilities and storage. (A) NPR and PR platelet counts are shown on the day of collection before splitting (day 1, before treatment), after splitting and with either no additional preparation or pathogen reduction treatment (day 1 post-treatment NPR and PR, respectively), and on subsequent experimental days (days 3, 5, 7, and 10). (B) Percentage of initial platelet count in NPR (orange) and PR (blue) platelet groups is shown over time. Individual data points from each trial are shown at each time point. ∗P < .05 comparing the difference between median NPR and PR platelets by 2-way ANOVA with the Tukey honestly significant difference test post hoc at the given time point.
