Congenital Anemia Due to Erythropoietin Gene Mutation Presenting With Diamond-Blackfan Anemia-like features.
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
Diamond-Blackfan anemia (DBA) is an inherited hypoplastic anemia, caused by mutations in ribosomal protein genes. Other mutations such as mutations in the erythropoietin (EPO) gene can lead to DBA-like (DBAL) through impairment of erythropoiesis. We present a 9-year-old patient with normocytic, normochromic, transfusion-dependent anemia since birth and reticulocytopenia. Bone marrow biopsies showed erythroid hypoplasia thereby excluding myelodysplasia and iron deficiency. Whole-exome sequencing revealed a homozygous mutation (c.530G>A; p.R177Q) in the EPO gene, which encodes a protein involved in erythroid progenitor-cell proliferation, confirmed the diagnosis of the DBAL. Diagnosis of congenital anemias has been complicated by their similar characteristics with DBA, but genetic testing is important in detecting rare causes of these disorders. This diagnosis enabled us to use recombinant human EPO therapy which reduced the need for blood transfusion.
