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

Studies of environmental enrichment are progressing in the fields of nervous system, stress and exercise. Recently, housing in enriched environment have shown to influence to carcinogenesis and life span. However, the study for antitumor effect of environmental enrichment are difficult to reproduce due to the complexity of the experimental technique. Thus, a simpler experiment system is needed for antitumor study using environmental enrichment. In this research, we propose a minimum environmental enrichment, which is an experimental system by placing one mouse igloo which is normally used as a mouse shelter in the rearing environment. The experimental system of minimum environmental enrichment is not only easy to reproduce but also have enhanced activity to suppress the growth of transplanted tumor significantly. It was found that the activation of NK cells is involved also in the immune system related to tumor immunity of minimum environmental enrichment. Because minimum environmental enrichment is effective in activating antitumor immunity to transplanted tumor cells in mice, we believe this will be useful for promoting antitumor studies using environmental enrichment.
