Vitamin K in photosynthetic organisms.
Review in Planta, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
MAIN
conclusionRecently, great progress in vitamin K research in plants was made, especially on vitamin K epoxide reductase (VKOR) homolog, new functions of VK in plant plasma membrane and VK1 biosynthesis. Although vitamin K (VK) was discovered in the 1930s, only recently has significant progress in the research on this lipid-soluble vitamin been made both in mammals and in photosynthetic organisms. For example, the molecular structure and catalytic mechanisms of the cyanobacterial vitamin K epoxide reductase (VKOR) homolog have been resolved. It has been recently shown that all organisms from bacteria to higher plants share common, phylogenetically related VKOR-type enzymes, engaged in the formation of disulfide bridges in various target proteins. This activity is related to the phylloquinone (VK1)-dependent regulation of the STN7 kinase, which is responsible for optimal energy distribution between two photosystems. Moreover, new functions of VK1 and menaquinone-4 (VK2) in plant plasma membrane electron transport chain were identified. Recently, the plastid-localized biosynthetic pathway of VK1 has been nearly completely recognized. However, there are also indications of an alternative, plasma membrane-targeted VK1 biosynthesis pathway.
