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

Connexin36 (Cx36) is highly expressed in inhibitory and excitatory neurons as well as pancreatic β-cells, where it forms gap junction channels that coordinate metabolic and electrical responses. In addition, Cx36 forms hemichannels in pancreatic β-cells, where it may play a critical role in endocrine cell signaling. Despite this, the regulatory mechanisms and biophysical properties of Cx36 HCs remain poorly understood. Using HeLa cells lacking endogenous expression of large-pore channels and transfected with mouse Cx36-EGFP, we evaluated hemichannel activity through dye uptake assays and membrane current recordings. We found that Cx36 hemichannel activity is strongly inhibited by extracellular Mg
