Structural and spectroscopic basis of excitation energy transfer in microbial rhodopsins binding xanthophylls.
Article in Chemical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
Carotenoids serve as accessory light-harvesting pigments in microbial rhodopsins, but the mechanisms enabling efficient energy transfer in systems lacking canonical 4-keto groups remain poorly understood. Here, we combine long-timescale molecular dynamics, polarizable quantum mechanics/molecular mechanics (QM/MM) calculations, and excitonic modeling to elucidate the structural and electronic factors that govern carotenoid-to-retinal excitation energy transfer (EET) in the proton-pumping rhodopsin Kin4B8. Focusing on the xanthophylls, zeaxanthin and lutein, we show they support ultrafast (<100 fs) and high-efficiency (≈70%) EET, enabled not by specific functional groups but by precise protein-ligand geometry. The carotenoid's β-ring is anchored
