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
backgroundPlatelet transfusion therapy has made a great breakthrough in clinical practice, and the differentiation of human embryonic stem cells (hESCs) to produce functional platelets has become a new potential approach, however, efficient generation of functional platelets still faces great challenges. Here, we presented a novel approach to highly and efficiently generate mature megakaryocytes (MKs) and functional platelets from hESCs.
methodsIn hypoxic conditions, we successfully replicated the maturation process of MKs and platelets in a controlled in vitro environment by introducing an optimal combination of cytokines at various stages of development. This method led to the generation of MKs and platelets derived from hESCs. Subsequently, mature MKs and functional platelets were further comprehensively investigated and characterized using a variety of methodologies, including flow cytometry analysis, RT-qPCR validation, Giemsa-Wright's staining, immunofluorescent staining, RNA transcriptome analysis, and DNA ploidy analysis. Additionally, the in vivo function of platelets was evaluated through the transplantation using thrombocytopenia model mice.
resultsUnder our 3D differentiation conditions with four sequential stages, hESCs could be efficiently induced into mature MKs, with 95% expressing CD41aCD42a or 90% expressing CD41aCD42b, and those MKs exhibited polyploid properties, produced filamentous proplatelet structures and further generated platelets. Furthermore, 95% of platelets showed CD42b
conclusionsThus, our results demonstrated that we successfully established a highly efficient differentiation of hESCs into mature MKs and functional platelets in vitro. The in vivo functionality of hESC-derived platelets closely resembles that of natural human platelets, thus offering a promising avenue for the development of functional platelets suitable for future clinical applications.
