An Agonist/Antagonist Photo-Switchable Vitamin D Mimetic Enables Bidirectional Optical Control of VDR.
Article in Angewandte Chemie (International ed. in English), 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
The secosteroid vitamin D (vitD) is essential for human health, maintaining bone metabolism, calcium homeostasis, and immune function via the vitamin D receptor (VDR). VDR activation has complex and cell-specific effects in multiple tissues and spatial control of VDR activity is desirable. Here, we developed vitD mimetics bearing a photo-switchable azobenzene motif to achieve spatiotemporal resolution in VDR activation. Structure-guided tuning of regiochemistry and H-bonding motifs provided a potent and selective vitD mimetic that can be reversibly switched in cellulo between agonist and antagonist states with light. In a model of osteogenesis, this unique bidirectional precision tool mediated light-dependent osteogenic and osteolytic effects.
