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

Gastrointestinal muscles are able to maintain negative resting membrane potentials in spite of stretch. We investigated whether stretch-dependent K+ channels might contribute to myogenic regulation of smooth muscle cells from the mouse colon. Negative pressure applied to on-cell membrane patches activated K+ channels that were voltage independent and had a slope conductance of 95 pS in symmetrical K+ gradients. The effects of negative pressure on open probability were graded as a function of pressure and reversible when atmospheric pressure was restored. Cell elongation activated K+ channels with the same properties as those activated by negative pressure, suggesting that the channels were stretch-dependent K+ (SDK) channels. Channels with the same properties were maximally activated by patch excision, suggesting that either an intracellular messenger or interactions with the cytoskeleton regulate open probability. Internal 4-aminopyridine, Ca2+ (10(-8) to 10(-6) M), and tetraethylammonium (internal or external) were without effect on SDK channels. Nitric oxide donors (and cell-permeant cGMP analogues) activated SDK channels, suggesting that these channels may mediate a portion of the enteric inhibitory neural response in colonic muscles. In summary, SDK channels are an important conductance expressed by colonic muscle cells. SDK channels may stabilize membrane potential during dynamic changes in cell length and mediate responses to enteric neurotransmitters.
