Exposure to sub-zero temperatures down to -11 °C does not impact packed red cells storage quality.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
European guidelines require packed red blood cells (pRBC) to be stored at 2-6 °C. However, negative temperature shifts can occur especially in prehospital transfusion. We investigated the impact of sub-zero temperature exposure on pRBC storage quality. At day 6 post donation (D6), three cohorts (14 pRBC) were put on a supercooled table for 10 h at either - 1 °C, -5 °C, and - 11 °C and compared to a control cohort. Hemolysis, pH and plasma biochemistry were evaluated weekly until D49. Storage-induced micro-erythrocytes (SMEs) were quantified as a surrogate marker for transfusion recovery. The primary endpoint was compliance with European storage standards at D42. The three sub-zero-exposed cohorts met standards at D42. Differences in hemolysis, pH, plasma biochemistry, or SMEs between exposed and control cohorts were non-statistically and/or non-clinically significant. Ten hours exposure to sub-zero temperatures down to -11 °C by conduction maintains storage quality of pRBCs, enabling a wiser risk assessment for potential transfusion use.
