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
The establishment, proliferation, and differentiation of stem cells are coordinated with organ development and regulated by the signals in the microenvironment. Prior to gonad formation, how primordial germ cells (PGC) differentiate spatiotemporally to coordinate with gonadogenesis is unclear. In adult ovary, drosophila extracellular glypican Dally in germline stem cell (GSC) niche promotes BMP signaling to inhibit germline differentiation. Here we investigated the relation between the fate of PGC and the spatiotemporal pattern of glypican during ovary development. We found that Dally in ovarian soma assisted BMP signaling to prevent PGC from precocious differentiation. Dally's presence raises the "hurdle" for ecdysone peaks to eventually remove the transcription factor Kr and de-repress pro-differentiation factor, temporally postponing PGC differentiation until GSC niche establishment. The spatiotemporal glypican in somatic matrix assists PGC to integrate the ovarian local BMP and organismal steroid signals that coordinate PGC's program with organ/body development to maximize reproductive potential.
