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
Induced pluripotent stem cell-derived immortalized megakaryocyte cell lines (imMKCLs) exhibit substantial heterogeneity, which poses a major barrier to efficient ex vivo production of platelet-like particles (PLPs). In this study, we combined proteomic profiling with principal component analysis to uncover regulatory factors influencing imMKCL maturation. Through correlation-based omics screening, prohibitin 2 (PHB2) was identified as a putative inhibitory node, and JI051, a small molecule previously reported to bind PHB2, was found to enhance PLP production. JI051 accelerated proplatelet-like extensions and increased PLP yield without affecting basic functional markers. Transcriptomic analysis showed that JI051 induced transcriptional changes consistent with megakaryocyte maturation and PLP biogenesis. Together, these findings identify JI051 as an enhancer of platelet biogenesis and provide a strategy to mitigate cellular heterogeneity in imMKCL megakaryocytes for scalable artificial platelet production, with potential benefits for emergency blood supply and cost-effective bioproduction.
