The open channel state in anion channelrhodopsin GtACR1 is a red-absorbing intermediate.
Article in Biophysical journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Anion channelrhodopsin GtACR1 is a powerful optogenetic tool to inhibit nerve activity. Its kinetic mechanism was interpreted in terms of the bacteriorhodopsin photocycle, and the L intermediate was assigned to the open channel state. Here, we report the results of the comparison between the time dependence of the channel currents and the time evolutions of the K-like and L-like spectral forms. Based on the results, we question the current view on GtACR1 kinetics and the assignment of the L intermediate to the open channel state. We report evidence for a red-absorbing intermediate being responsible for channel opening.
