2 a, left panel and Table 1 , OR = 1.05, se = 0.38, p = 0.89), the ability of cryo-preserved RBCs to culture infectious gametocytes showed a marginally insignificant decline with duration of storage (Fig. 2 b, left panel and Table 1 , OR = 0.89, se = 0.06, p = 0.07) with much of the unexplained variation represented by differences across experimental blocks (Table 1 and Additional file 5 b), although some could also be attributed to RBC donor characteristics (Fig. 2 b, left panel, Table 1 and Additional file 5 b).
