Kv2.1 ablation alters glucose-induced islet electrical activity, enhancing insulin secretion.
Article in Cell metabolism, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 108 papers.
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
Voltage-gated potassium currents (Kv), primarily due to Kv2.1 channels, are activated by glucose-stimulated pancreatic beta cell depolarization, but the exact role (or roles) of this channel in regulating insulin secretion remains uncertain. Here we report that, compared with controls, Kv2.1 null mice have reduced fasting blood glucose levels and elevated serum insulin levels. Glucose tolerance is improved and insulin secretion is enhanced compared to control animals, with similar results in isolated islets in vitro. Isolated Kv2.1(-/-) beta cells have residual Kv currents, which are decreased by 83% at +50 mV compared with control cells. The glucose-induced action potential (AP) duration is increased while the firing frequency is diminished, similar to the effect of specific toxins on control cells but substantially different from the effect of the less specific blocker tetraethylammonium. These results reveal the specific role of Kv2.1 in modulating glucose-stimulated APs of beta cells, exposing additional important currents involved in regulating physiological insulin secretion.
