1 · What the graph read from it

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.

2 · The registry

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

In addition to the extensive gap junction coupling between astrocytes themselves, oligodendrocytes are thought to be exclusively coupled to astrocytes (O:A coupling) via heterotypic gap junctions composed of Cx47:Cx43 and Cx32:Cx30. We used fluorescent dyes to examine functional coupling in acute slices from the cerebra of mice lacking Cx32 and/or Cx47. In the corpus callosum, unexpectedly, oligodendrocytes appeared to be directly and exclusively coupled to other oligodendrocytes (O:O coupling), and electron microscopy revealed gap junctions between adjacent oligodendrocytes. O:O coupling was more affected in mice lacking Cx32 than in mice lacking Cx47. In the neocortex, oligodendrocytes appeared to be directly and exclusively coupled to astrocytes; Cx47, but not Cx32, was required for O:A coupling.
