Porcine Packed Red Blood Cells Demonstrate a Distinct Red Blood Cell Storage Lesion.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe red blood cell (RBC) storage lesion has been well described in mouse and human blood but not in swine. Understanding the porcine RBC storage lesion is necessary prior to evaluating transfusion of stored packed red blood cells (pRBCs) in polytrauma models. We hypothesized that porcine pRBCs would undergo a similar storage lesion severity after 42 d.
methodsWhole blood was collected from female Yorkshire pigs and pRBCs were isolated in additive storage solution 3. Female human whole blood was obtained from our local blood bank and pRBCs prepared. Human and porcine pRBCs were stored for 42 d and sampled weekly and evaluated for markers of the RBC storage lesion including biochemical measurements, eryptotic RBCs, band-3 expression, erythrocyte-derived microvesicles, and free hemoglobin concentrations.
resultsPorcine pRBCs demonstrated a hematocrit similar to human pRBCs. Both human and porcine pRBC units developed a progressive storage lesion. However, over 42 d of storage, porcine pRBCs maintained their pH and had decreased glucose utilization. Porcine pRBCs also demonstrated decreased levels of eryptosis compared to human samples and generated less erythrocyte-derived microvesicles with lower free hemoglobin concentrations.
conclusionsPorcine pRBCs stored in additive storage solution 3 demonstrate a progressive RBC storage lesion over 42 d of storage but with less severity than human controls. Given the differences in porcine erythrocyte metabolism, further study of the storage lesion in porcine blood is needed in addition to incorporating the use of stored porcine pRBCs in a swine model of hemorrhagic shock to more closely mimic clinical scenarios.
