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

Photosystem I (PSI) is one of the two photosystems conserved from cyanobacteria to vascular plants, and associates with multiple light-harvesting complexes (LHCs) that capture and transfer solar energy. Liverworts such as Marchantia polymorpha occupy an early evolutionary position among land plants and faced major challenges during terrestrial adaptation, including desiccation, strong light, and UV radiation. We reveal the cryo-electron microscopic structures of PSI-LHCI monomer and homodimer from the liverwort M. polymorpha at resolutions of 1.94 and 2.52 Å, respectively. The high-resolution map allows identification of the cofactors of the monomer and reveal differences between the liverwort and moss, another clade of bryophytes. The PSI-LHCI monomer-monomer is stabilized by PsaG and PsaH interactions on the stromal side, which causes the bending and twisting of the homodimer. PsaM interacts with PsaB tightly, indicating a key role of PsaM in mediating the dimerization.
