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

Ten new 3,4-seco betulinic acid (BA) derivatives were designed and synthesized. Among them, compounds 7-15 exhibited enhanced chemopreventive ability in an in vitro short-term 12-O-tetradecanoylphorbol-13-acetate (TPA) induced Epstein-Barr virus early antigen (EBV-EA) activation assay in Raji cells. Specifically, analogs with a free C-28 carboxylic acid, including 7, 8, 11, and 13, inhibited EBV-EA activation significantly. The most potent compound 8 displayed 100% inhibition at 1×10(3) mol ratio/TPA and 73.4%, 35.9%, and 8.4% inhibition at 5×10(2), 1×10(2), and 1×10 mol ratio/TPA, respectively, comparable with curcumin at high concentration and better than curcumin at low concentration. The potent chemopreventive activity of novel seco A-ring BAs (8 and 11) was further confirmed in an in vivo mouse skin carcinogenesis assay.
