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

Human NHE6 (HsNHE6) is an endosomal Na⁺/H⁺ exchanger essential for maintaining luminal pH and endo-lysosomal trafficking in neurons. HsNHE6 mutations are implicated in devastating neurological syndromes, but mechanistically the transporter remains poorly understood. Here, we present the single-particle cryo-electron microscopy (cryo-EM) structure of HsNHE6 at 3.4 Å, captured in an inward-facing conformation. The structure reveals a homodimeric architecture with 13 transmembrane helices per protomer, with the conserved ion-binding site located at the interface of the core and dimerization domains. Functional assays demonstrate that HsNHE6 reconstituted in liposomes exchanges Na⁺, K⁺, Li⁺, and Rb
