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

Potassium-selective ion channels regulate cardiac and neuronal excitability by stabilizing the resting membrane potential and by modulating shape and frequency of action potentials. The delicate control of membrane voltage requires structural and functional diversity of K+ channel subunits expressed in a given cell. Here we reveal a previously unrecognized biological mechanism. Tissue-specific mRNA splicing regulates alternative translation initiation (ATI) of human K(2P)10.1 K+ background channels via recombination of 5 nucleotide motifs. ATI-dependent expression of full-length protein or truncated subunits initiated from two downstream start codons determines macroscopic current amplitudes and biophysical properties of hK(2P)10.1 channels. The interaction between hK(2P)10.1 mRNA splicing, translation and function increases K+ channel complexity and is expected to contribute to electrophysiological plasticity of excitable cells.
