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

purposeEpigallocatechin-3-gallate (EGCG) is an antioxidant agent derived from green tea. Because it has chemopreventive and anti-invasive effect against various cancer cells, EGCG can be used to inhibit proliferation and invasion of cholangiocarcinoma (CCA) cells.

methodsThe anticancer effects of EGCG were studied using human CCA cells (HuCC-T1). Apoptosis was analyzed by Western blotting. Invasion and migration of cancer cells were assessed with Matrigel

resultsEGCG effectively inhibited the growth of HuCC-T1 cells with no adverse effects on the viability of 293T cells. EGCG induced apoptotic cell death at 5 µg/mL concentration. It inhibited the expression of mutant p53 and induced apoptotic molecular signals such as Bax/Bcl-2, Caspase, and cytochrome C. Furthermore, EGCG dose-dependently inhibited the activity of matrix metalloproteinase (MMP)-2/9, invasion, and migration. In the animal tumor xenograft model of HuCC-T1 cells, EGCG was subcutaneously administered beside the tumor for local treatment. EGCG efficiently inhibited growth of the tumor and suppressed carcinogenic molecular signals such as Notch1, MMP-2/9, and proliferating cell nuclear antigen.

conclusionEGCG induced apoptosis of cancer cells without adverse effects on normal cells. EGCG inhibited growth, invasion, and migration of HuCC-T1 cells. We suggest EGCG as a promising candidate for local treatment of CCA.
