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
In vitro red blood cell (RBC) production offers a promising complement to conventional blood donation, particularly for patients with rare blood types. Previously, we developed imBMEP-A, the first erythroid cell line derived from reticulocyte progenitors, which maintains robust hemoglobin expression and erythroid differentiation in the presence of erythropoietin (EPO) despite its immortalized state. However, clinical translation remains hindered by the inability to scale up production due to impaired in vitro enucleation of RBC progenitor cell lines. Enhancing enucleation efficiency in imBMEP-A cells involved CRISPR/Cas9-mediated knockout (K.O.) of miR-30a-5p, a key enucleation inhibitor, moderately increasing rates to 3.3 ± 0.4%- 8.9 ± 1.7%. Further investigation of enucleation inefficiencies led to transcriptome and proteome comparisons between imBMEP-miR30a-K.O. cells and hematopoietic stem cells (HSCs). These analyses revealed altered gene expression and protein abundances linked to metabolic transitions, apoptosis promotion, and cytoskeletal regulation. Notably, forced expression of the proto-oncogene c-Myc, required for cell immortalization, emerged as a key driver of these physiological changes. Counteracting these effects required optimization of imBMEP-A cells by activating BCL-XL transcription and knocking out SCIN, which encodes the actin-severing protein scinderin. While BCL-XL is upregulated in normal erythropoiesis, it is downregulated in imBMEP-A. Conversely, SCIN, typically absent in erythroid cells, is highly expressed in imBMEP-A, disrupting actin organization. These interventions improved viability, restored actin network formation, and increased terminal erythropoiesis, yielding 22.1 ± 1.7% more orthochromatic erythroblasts. These findings establish a foundation for optimizing imBMEP-A cells for therapeutic use and advancing the understanding the pathophysiology of erythroleukemia.
