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

MiR-195 has been implicated in inhibiting cell proliferation in different types of tumors. Whether it contributes to the process of thymic epithelial cells (TECs) proliferation remains unclear. In this study, we found that miR-195a-5p was highly up-regulated in the TECs isolated from the aging mice. Further experiments showed that miR-195a-5p mimic transfection inhibited the proliferation of mouse medullary thymic epithelial cell line 1 (MTEC1), whereas the transfection of miR-195a-5p inhibitor in MTEC1 had the opposite effect. In addition, miR-195a-5p had no obvious effect on MTEC1 apoptosis. Furthermore, Smad7, a negative regulator of transforming growth factor β pathway, was confirmed as a direct target of miR-195a-5p by luciferase assays. Taken together, our results indicate that miR-195a-5p inhibits MTEC1 proliferation, at least in part, via down-regulation of Smad7.
