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
Pure red cell aplasia (PRCA) is a rare disorder characterized by a significant reduction in red blood cell production. A 65-year-old man with myelodysplastic syndrome and monoclonal gammopathy of undetermined significance developed acquired PRCA (aPRCA) 2 weeks after receiving the BNT162b2 mRNA coronavirus disease 2019 vaccine, with Epstein-Barr virus DNA detected at the onset. The patient did not respond to immunosuppressive therapy and required red blood cell transfusion every one to two weeks. Although the causal relationship between vaccination and aPRCA remains unclear, adequate attention should be paid to post-vaccination aPRCA in patients with hematological disorders.
