1 · What the graph read from it

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.

2 · The registry

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

The designation of O RhD-negative blood as a "universal donor" misrepresents the complexity of red blood cell (RBC) compatibility. With 47 recognized blood group systems encompassing 366 antigens, non-ABO antigen exposure drives alloimmunization in 20-50% of chronically transfused patients. A narrative review of PubMed, Scopus, and EMBASE was conducted for studies published between 2016 and 2025, with selective inclusion of foundational pre-2016 works. Enzymatic approaches using Flavonifractor plautii CAZymes and Akkermansia muciniphila exoglycosidase cocktails enable near-complete ABO antigen removal, though group A conversion remains incomplete. CRISPR-Cas9 multiplex editing of immortalized erythroblasts has achieved simultaneous deletion of ABO, Rh, Kell, Duffy, and MNS antigens. Induced pluripotent stem cell platforms enable scalable manufacture; however, enucleation efficiency (40-70%), yield (4.6 × 10
