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

Solute carrier family 26 (SLC26) mainly mediates transmembrane transport of various anion ions, including chloride and other halide ions, bicarbonate, oxalate, and sulfate. Many severe hereditary human diseases are correlated with SLC26 protein mutations. Here we report cryo-EM structures of human SLC26A7 in apo and iodide binding states. We identify non-canonical binding site for halide ions in SLC26A7. Molecular dynamics simulation and electrophysiological assay confirm the functional importance of key residues involved in iodide and chloride coordination. Together, our discovery marks a step towards an in-depth understanding of SLC26 family protein transport mechanisms.
