Article in Biochemistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Ligand-triggered activation of G protein-coupled receptors (GPCRs) relies on the phenomenon of loose allosteric coupling, which involves conformational alterations spanning from the extracellular ligand-binding domain to the cytoplasmic region, where interactions with G proteins occur. During the GPCR activation process, several intermediate and equilibrium states orchestrate the movement of the flexible and rigid transmembrane (TM) segments of the GPCR. Monitoring early conformational changes is important in unraveling the structural intricacies of the loose allosteric coupling. Here, we focus on the lumi intermediate formed by thermal relaxation from the initial photointermediate, batho in primate green cone pigment (MG), a light-sensitive GPCR responsible for color vision. Our findings from light-induced Fourier transform infrared difference spectroscopy reveal its similarity with rhodopsin, which mediates twilight vision, specifically involving the flip motion of the β-ionone ring, the relaxation of the torsional structure of the retinal, and local perturbations in the α-helix upon lumi intermediate formation. Conversely, we observe a hydrogen bond modification specific to MG's protonated carboxylic acid, identifying its origin as Glu102
