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

A growing number of mutations are being identified in the noncoding genome, including microRNA (miRNA) genes; however, little is known about the consequences of these mutations and how harmful they are to the functioning of miRNA genes. To evaluate the effects of miRNA gene mutations, we took advantage of a large collection of somatic mutations identified in miRNA genes in >10,000 The Cancer Genome Atlas cancer samples and compared them with the corresponding miRNA sequencing data. Using different analytical approaches and rigorous statistical criteria, we revealed that a substantial fraction of mutations is deleterious for the proper functioning of miRNA genes affecting the level of mature miRNAs, isomiR profiles (precision of DROSHA/DICER1 cleavage), and/or 5p/3p miRNA strand balance. We also showed that most mutations, especially those identified as deleterious, destabilize the structure of miRNA precursors. The analysis showed that many miRNA gene mutations can damage miRNA genes and, if located in disease-related miRNA genes, may be pathogenic variants.
