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

Tormentic acid (TA) is a triterpene isolated from the stem bark of the plant Vochysia divergens and has been reported to exhibit anticancer, anti‑inflammatory and anti‑atherogenic properties. However, the functions of TA in hydrogen peroxide (H2O2)‑induced oxidative stress and inflammation in rat vascular smooth muscle cells (RVSMCs) remain unclear. Therefore, the present study aimed to investigate whether TA suppressed H2O2‑induced oxidative stress and inflammation in RVSMCs, and to determine its molecular mechanisms. The present study demonstrated that TA inhibited reactive oxygen species (ROS) generation, induced H2O2 in RVSMCs, and inhibited H2O2-induced expression of inducible nitric oxide synthase (iNOS) and NADPH oxidase (NOX) in RVSMCs. In addition, TA significantly decreased the production of tumor necrosis factor‑α (TNF‑α), interleukin 6 (IL‑6) and IL‑1β. Furthermore, TA pretreatment prevented nuclear factor‑κB (NF‑κB) subunit p65 phosphorylation and NF‑κB inhibitor α (IκBα) degradation induced by H2O2 in RVSMCs. TA is, therefore, suggested to inhibit H2O2-induced oxidative stress and inflammation in RVSMCs via inhibition of the NF‑κB signaling pathway. TA may have potential as a pharmacological agent in the prevention or treatment of atherosclerosis.
