DNA Methyl Transferase 3A (DNMT3A) Mutation Presenting as Isolated Pure Red Cell Aplasia.
Article in Journal of investigative medicine high impact case reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 mainly affecting the erythroid precursor cells. It presents with severe isolated reticulocytopenia with relatively normal counts in the myeloid and megakaryocytic lineages. It has been attributed to numerous congenital and acquired causes. DNA Methyl Transferase 3 Alpha (DNMT3A) mutation has been typically associated with myeloid and lymphoid malignancies. There is a scarcity of data regarding the association of DNMT3A mutation with PRCA. We report a case of a 73-year-old man who initially presented with anemia and reticulocytopenia. After a thorough evaluation and eventual bone marrow biopsy, he was diagnosed with PRCA. Further genetic testing identified a DNMT3A mutation. We are reporting this rare case to highlight the fact that DNMT3A mutation can also present as isolated PRCA in and of itself without the co-occurrence of leukemia, lymphoma, or myelodysplastic syndrome (MDS).
