Donor genetics and storage conditions influence mitochondrial DNA and extracellular vesicle levels in RBC units.
Article in JCI insight, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Mitochondrial DNA (mtDNA) shares characteristics with bacterial DNA and activates immune cells via TLR9Extracellular vesicles (EVs) and mtDNA have been found in blood products and can activate immune cells; we sought to characterize their evolution in stored blood products. From a previous study of hemolysis in 13,403 blood donors, a second blood unit was drawn from 651 donors and sampled at days 10, 21, and 42. EV counts and RBC-EVs increased with storage time, and EV levels were higher in males and in RBC units processed in AS-1 compared with AS-3. mtDNA levels were higher in females and RBC units processed in AS-3. EV populations and mtDNA levels were highly correlated within donors for 98 donations obtained 2-12 months apart. Quantitative trait locus analysis revealed several genetic associations, most notably linking mtDNA levels with polymorphisms in ANKLE1, which encodes an erythroid-specific protein that preferentially cleaves mtDNA. These data suggest that donor-intrinsic factors may influence mtDNA and EV levels found in RBC units. This finding lends impetus to determining if genetic or environmental factors control levels of these immune mediators in blood donors.
