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

Red wine compounds have been reported to reduce the rate of atherosclerosis by inducing nitric oxide (NO) production and antioxidant enzyme expression in vascular endothelial cells (VECs). The present study compared the effects of the three red wine compounds resveratrol and its dimers, ε-viniferin and δ-viniferin, on VECs function for the first time. Both 5 μM ε-viniferin and δ-viniferin, but not 5 μM resveratrol, significantly stimulated wound repair of VECs. Increased levels of wound repair induced by 10 and 20 μM ε-viniferin were significantly higher than those stimulated by 10 and 20 μM resveratrol, respectively. These stimulatory effects of the three compounds were suppressed by the NO synthase inhibitor L-NAME. When VECs were exposed to each compound, endothelial NO synthase was activated and the expression of sirtuin 1 (SIRT1) and HO-1 was induced. Addition of the SIRT1 and HO-1 inhibitors EX527 and ZnPPiX, respectively, suppressed wound repair stimulated by the three compounds, demonstrating that SIRT1 and HO-1 are involved in these wound repair processes. Furthermore, each compound induced the suppression of H
