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
Somatic cell reprogramming into induced pluripotent stem cells (iPSCs) has been achieved in various mammals; however, assessing iPSC contribution to full-term chimeras beyond laboratory rodents remains challenging. Here, we demonstrate induction of pluripotency in male and female fibroblasts from the African pygmy mouse (APM), one of the smallest mammals. Using transcription factors and small molecules, we derived expandable APM-iPSCs that express pluripotency markers, differentiate into various cell types in vitro, and form gastruloids. Injection of APM-iPSCs into house mouse blastocysts generated full-term interspecies chimeras demonstrating extensive contribution to various tissues, including testicular germ cells. Notably, high APM contribution in organs such as heart and testes correlated with reduced organ size compared with mouse organs. Lastly, injection of APM-iPSCs into mouse blastocysts carrying a Pax7 ablation system enabled substantial production of APM muscle stem cells in chimeras. Collectively, this study establishes APM-iPSCs as a developmental model for pluripotency, differentiation, and interspecies chimerism.
