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
D6 is a promoter/enhancer of the mDach1 gene that is involved in the development of the neocortex and hippocampus. It is expressed by proliferating neural stem/progenitor cells (NSPCs) of the cortex at early stages of neurogenesis. The differentiation potential of NSPCs isolated from embryonic day 12 mouse embryos, in which the expression of green fluorescent protein (GFP) is driven by the D6 promoter/enhancer, has been studied in vitro and after transplantation into the intact adult rat brain as well as into the site of a photochemical lesion. The electrophysiological properties of D6/GFP-derived cells were studied using the whole-cell patch-clamp technique, and immunohistochemical analyses were carried out. D6/GFP-derived neurospheres expressed markers of radial glia and gave rise predominantly to immature neurons and GFAP-positive cells during in vitro differentiation. One week after transplantation into the intact brain or into the site of a photochemical lesion, transplanted cells expressed only neuronal markers. D6/GFP-derived neurons were characterised by the expression of tetrodotoxin-sensitive Na(+)-currents and K (A)- and K (DR) currents sensitive to 4-aminopyridine. They were able to fire repetitive action potentials and responded to the application of GABA. Our results indicate that after transplantation into the site of a photochemical lesion, D6/GFP-derived NSPCs survive and differentiate into neurons, and their membrane properties are comparable to those transplanted into the non-injured cortex. Therefore, region-specific D6/GFP-derived NSPCs represent a promising tool for studying neurogenesis and cell replacement in a damaged cellular environment.
