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

MicroRNAs are small noncoding RNAs that carry out post-transcriptional regulation of the expression of their target genes. However, their roles in mammalian organogenesis are only beginning to be understood. Here we show that the microRNA-212/132 family (which comprises miR-212 and miR-132) is indispensable during the development of the mammary glands in mice, particularly for the regulation of the outgrowth of the epithelial ducts. Mammary transplantation experiments revealed that the function of the miR-212/132 family is required in the stroma but not in the epithelia. Both miR-212 and miR-132 are expressed exclusively in mammary stroma and directly target the matrix metalloproteinase MMP-9. In glands that lack miR-212 and miR-132, MMP-9 expression increases and accumulates around the ducts. This may interfere with collagen deposition and lead to hyperactivation of the tumor growth factor-β signaling pathway, thereby impairing ductal outgrowth. Our results identify the miR-212/132 family as one of the main regulators of the epithelial-stromal interactions that are required for proper pubertal development of the mammary gland.
