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

Isofraxidin, a characteristic coumarin extracted from the root of Sarcandra glabra, prevents human hepatoma cell invasion, while its biosynthesis remains elusive. Here, we construct a 4.23-Gb chromosome-level genome of S. glabra. We find that its intergenic and genic regions are profoundly longer than those of other angiosperms. Among the root-enriched O-methyltransferase candidates, SgOMT3 produces comparable amounts of isofraxidin and the byproduct fraxidin from fraxetin, while SgOMT5 only produces fraxidin. SgOMT3 and SgOMT5 are dispersed duplication genes, and site-directed mutagenesis reveals that Leu127 in SgOMT3 and Val292 in SgOMT5 are the key residues for isofraxidin and fraxidin biosynthesis, respectively. SgOMT3 orthologs from eudicot species preferentially produce more isofraxidin than fraxidin. The molecular docking and site-directed mutagenesis reveal that a Leu-to-Ile substitution at position 307 alters the regioselectivity of SgOMT3, shifting the conversion predominantly toward isofraxidin. These findings accelerate germplasm improvement of S. glabra and provide evidence for isofraxidin biosynthesis in chassis.
