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
Culture platforms for human induced pluripotent stem cells (hiPSCs) that rely on feeder cells or extracellular matrices (ECMs) face substantial limitations for practical regenerative medicine applications, including undefined components, high costs, and a tendency to maintain hiPSCs in the primed pluripotent state, which has lower differentiation potential than the naïve state. To overcome these challenges, we developed a long-term hiPSC culture platform based on a cross-linked cyclosiloxane polymer matrix that preserves pluripotency with naïve-like characteristics. Through optimization, we identified an ideal cyclosiloxane polymer matrix, designated as poly-Z, which supported the growth of hiPSCs as spheroids. Even after 60 d of continuous culture, hiPSC spheroids maintained on poly-Z retained pluripotency markers and normal karyotypes at levels comparable to those of hiPSC colonies cultured on conventional vitronectin (VN)-coated plates. Furthermore, mRNA sequencing revealed that hiPSC spheroids cultured on poly-Z not only exhibited up-regulation of typical pluripotency-related genes but also showed increased expression of genes associated with the naïve pluripotent state, in contrast to the primed state observed in hiPSCs cultured on VN-coated plates or in suspension culture. Gene ontology (GO) analysis and gene set enrichment analysis (GSEA) further suggested that the down-regulation of genes involved in cell-ECM interactions contributed to the induction of naïve-like features in poly-Z-cultured hiPSC spheroids. These findings highlight the potential of cross-linked cyclosiloxane-based polymer matrices as an innovative platform for human pluripotent stem cell research and regenerative medicine.
