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
key messageCYP72D19, the first functional gene of the CYP72D subfamily, catalyzes the C-2 hydroxylation of abietane-type diterpenoids. The abietane-type diterpenoids, e.g., triptolide, tripdiolide, and 2-epitripdiolide, are the main natural products for the anti-tumor, anti-inflammatory, and immunosuppressive activities of Tripterygium wilfordii, while their biosynthetic pathways are not resolved. Here, we cloned and characterized the CYP72D19-catalyzed C-2 hydroxylation of dehydroabietic acid, a compound that has been proven to be a biosynthetic intermediate in triptolide biosynthesis. Through molecular docking and site-directed mutagenesis, L386, L387, and I493 near the active pocket were found to have an important effect on the enzyme activity, which also indicates that steric hindrance of residues plays an important role in function. In addition, CYP72D19 also catalyzed a variety of abietane-type diterpenoids with benzene ring, presumably because the benzene ring of the substrate molecule stabilized the C-ring, allowing the protein and the substrate to form a relatively stable spatial structure. This is the first demonstration of CYP72D subfamily gene function. Our research provides important genetic elements for the structural modification of active ingredients and the heterologous production of other 2-hydroxyl abietane-type natural products.
