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
Purpose: The proliferative and neurogenic potential of retinal Müller glia after injury varies widely across species. To identify the endogenous mechanisms regulating the proliferative response of mammalian Müller glia, we comparatively analyzed the expression and function of nestin, an intermediate filament protein established as a neural stem cell marker, in the mouse and rat retinas after injury. Methods: Nestin expression in the retinas of C57BL/6 mice and Wistar rats after methyl methanesulfonate (MMS)-induced photoreceptor injury was examined by immunofluorescence and Western blotting. Adeno-associated virus (AAV)-delivered control and nestin short hairpin RNA (shRNA) were intravitreally injected to rats and Müller glia proliferation after MMS-induced injury was analyzed by BrdU incorporation and immunofluorescence. Photoreceptor removal and microglia/macrophage infiltration were also analyzed by immunofluorescence. Results: Rat Müller glia re-entered the cell cycle and robustly upregulated nestin after injury whereas Müller glia proliferation and nestin upregulation were not observed in mice. In vivo knockdown of nestin in the rat retinas inhibited Müller glia proliferation while transiently stimulating microglia/macrophage infiltration and phagocytic removal of dead photoreceptors. Conclusions: Our findings suggest a critical role for nestin in the regulation of Müller glia proliferation after retinal injury and highlight the importance of cross species analysis to identify the molecular mechanisms regulating the injury responses of the mammalian retina.
