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.
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
The human sarcomeric myosin heavy chain gene MYH14 contains an intronic microRNA, miR-499. Our previous studies demonstrated divergent genomic organization and expression patterns of myh14/miR-499 among teleosts; however, the regulatory mechanism is partly known. In this study, we report the regulation of myh14 expression in zebrafish, Danio rerio. Zebrafish myh14 has three paralogs, myh14-1, myh14-2, and myh14-3. Detailed promoter analysis suggested that a 5710-bp 5'-flanking region of myh14-1 and a 5641-bp region of myh14-3 contain a necessary regulatory region to recapitulate specific expression during embryonic development. The 5'-flanking region of zebrafish myh14-1 and its torafugu ortholog shared two distal and a single proximal conserved region. The two distal conserved regions had no effect on zebrafish myh14-1 expression, in contrast to torafugu expression, suggesting an alternative regulatory mechanism among the myh14 orthologs. Comparison among the 5'-flanking regions of the myh14 paralogs revealed two conserved regions. Deletion of these conserved regions significantly reduced the promoter activity of myh14-3 but had no effect on myh14-1, indicating different cis-regulatory mechanisms of myh14 paralogs. Loss of function of miR-499 resulted in a marked reduction in slow muscle fibers in embryonic development. Our study identified different cis-regulatory mechanisms controlling the expression of myh14/miR-499 and an indispensable role of miR-499 in muscle fiber-type specification in zebrafish.
