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

Metastasis remains one of the major challenges before hepatocellular carcinoma (HCC) is finally conquered. Estrogen has recently emerged as a protective factor in the development and progression of HCC, but whether and how it reduces metastasis of HCC remain to be elucidated. We conducted an in vivo highly metastatic rat HCC model in female Sprague-Dawley rats induced by diethylnitrosamine and N-nitrosomorpholine to examine the effects of estrogen on HCC metastasis. Moreover, female rats were randomly distributed into four groups: ovariectomy (OVX), sham operation, ovariectomy followed by 30 μg/kg body weight/day 17α-ethynylestradiol supplementation, and sexually intact control groups. Here, we show that, 60% lung metastasis was observed in the rats of OVX group, whereas 17-25% lung metastasis was found in rats of the other three groups. Furthermore, physiological doses of estrogen, no matter endogenous or exogenous, can suppress metastasis of HCC through decreasing interleukin-6 (IL-6) and hepatocyte growth factor (HGF) expression in the tumor microenvironment. In conclusion, the present study demonstrated that estrogen has the potential to inhibit lung metastasis from rat HCCs in vivo. Its mechanism of action may involve modulation of inflammatory tumor microenvironment by suppression of HGF and IL-6 production.
