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

Channelrhodopsins (ChRs) are photoreceptors that function as light-gated ion channels. Over the last two decades, they have become essential tools in optogenetics, enabling precise manipulation of neurons, neural circuits, and animal behavior through light. Although structural studies have provided important mechanistic insights into channelrhodopsins, a detailed understanding of their ion conduction mechanism and selectivity was proven to be challenging due to difficulties in experimentally resolving open-state structures. Here, we employed molecular dynamics (MD)-based computational electrophysiology and constant-pH simulations to obtain the fully open states of three different ChRs. A significant number of spontaneous K
