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 an attempt to define the molecular basis of the functional diversity of K+ channels, we have isolated overlapping rat brain cDNAs that encoded a neuronal delayed rectifier K+ channel, K,4, that is structurally related to the Drosophila Shaw protein. Unlike previously characterized mammalian K+ channel genes, which each contain a single protein-coding exon, K,4 arises from alternative exon usage at a locus that also encodes another mammalian Shaw homolog, NGK2. Thus, the enormous diversity of K+ channels in mammals can be generated not just through gene duplication and divergence but also through alternative splicing of RNA.
