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

The pineal hormone melatonin has been shown to have anticancer therapeutic properties in patients with gastric cancer, the mechanisms, however, remain largely unknown. The present study examined the effects of melatonin on cell differentiation related factors, namely, endocan, alkaline phosphatase, and lactate dehydrogenase, in gastric adenocarcinoma cell line SGC7901. Expression of endocan was significantly decreased in tissue of gastric cancer as compared to normal stomach tissue, as determined by immunohistochemical staining, and there is correlation between the degree of the decrease of endocan expression and the degree of differentiation of the cancer. Treatment of cultured gastric adenocarcinoma cells with 10(-4) mol/l melatonin significantly increased the gene expression of endocan and down-regulated the activity of alkaline phosphatase and lactate dehydrogenase, two enzymes that promote de-differentiation in gastric tissue; and there was a negative correlation between the level of endocan expression and the activities of differentiation marker enzymes in the melatonin treated cancer cells. Gastric cancer cells treated with melatonin show more differentiated morphologic phenotype as compared the untreated cells. The findings indicate that melatonin may play its anticancer role in gastric adenocarcinoma by acting as a differentiation inducer.
