Long‐stored ('older') PRBC (≥ 21 days of storage) vs short‐stored (fresh) PRBC (< 21 days of storage): Death from any cause
It is very uncertain whether long‐stored ('older') PRBC (≥ 21 days of storage) changes death from any cause compared with short‐stored (fresh) PRBC (< 21 days of storage) (very low certainty).

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
