Long‐stored ('older') PRBC (≥ 21 days of storage) vs short‐stored (fresh) PRBC (< 21 days of storage)

Death from any cause · patients requiring blood transfusion (children with malaria and adults with a traumatic injury)

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).
