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

Volume-regulated anion channels (VRACs) encoded by the LRRC8 gene family play essential roles in diverse and fundamentally important physiological processes in vertebrate cells. The recent determination of high-resolution cryo-electron microscopy (cryo-EM) structures of homomeric and heteromeric LRRC8 channel complexes has created unprecedented opportunities for understanding the molecular basis of VRAC structure, function and pharmacology. Native LRRC8 channels are obligatory heteromers composed of at least one LRRC8A subunit together with one of the other paralogues (LRRC8B-E) with an unknown stoichiometry. This heteromeric nature of endogenously expressed VRACs and the difficulties associated with controlling the composition and stoichiometry of heterologously expressed LRRC8 channels present considerable experimental challenges. The development of LRRC8 chimeras, which exhibit normal functional and regulatory properties and that can be expressed as homomeric channels, circumvents many of these challenges. In this review, we discuss the recent advances in the structural characterization of LRRC8 channels, with a primary focus on the cryo-EM structures of one such chimera, created by swapping 25 residues from LRRC8A subunits to LRRC8C subunits and termed as 8C-8A(IL1
