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

Hearing loss ranks fourth among the principal causes of disability worldwide, and manipulation of progenitor cells may be a key strategy for hair cell regeneration. The present study investigated the role and mechanism of miR‑125 on the proliferation of cochlear progenitor cells (CPCs). CPCs were isolated from the cochleae of neonatal rats, and their morphology was observed. Furthermore, the differentiation ability of CPCs was determined by assessing the expression of 5‑bromodeoxyuridine (BrdU), nestin and myosin VII by immunofluorescence. The expression levels of miR‑125 and cyclin‑dependent kinase 2 (CDK2) as well as the cell proliferation of CPCs were assessed. In addition, following gain‑ and loss‑of‑function assays, the cell cycle was examined by flow cytometry, and the expression levels of miR‑125, CDK2, proliferating cell nuclear antigen (PCNA) and nestin were determined by reverse transcription‑quantitative PCR and western blotting. The binding sites between miR‑125 and CDK2 were predicted by TargetScan and identified by the dual luciferase reporter assay. The results demonstrated that different types of progenitor spheres were observed from CPCs with positive expression of BrdU, nestin and myosin VII. Following
