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
MicroRNAs (miRNAs) are involved in regulating the circadian clock. In our previous work, miR-218-5p was found to be a circadian miRNA in the chicken uterus, but its role in the eggshell formation process was not clear. In the present study, we found that the expression levels of miR-218-5p and two 2 predicted target genes carbonic anhydrase 2 (CA2) and neuronal PAS domain protein 2 (NPAS2) were oscillated in the chicken uterus. The results of dual-luciferase reporter gene assays in the present study demonstrated that miR-218-5p directly targeted the 3' untranslated regions of CA2 and NPAS2. miR-218-5p showed an opposite expression profile to CA2 within a 24 h cycle in the chicken uterus. Moreover, over-expression of miR-218-5p reduced the mRNA and protein expression of CA2, while miR-218-5p knockdown increased CA2 mRNA and protein expression. Overexpression of CA2 also significantly increased the activity of carbonic anhydrase Ⅱ (P < 0.05), whereas knockdown of CA2 decreased the activity of carbonic anhydrase Ⅱ. miR-218-5p influenced carbonic anhydrase activity via regulating the expression of CA2. These results demonstrated that clock-controlled miR-218-5p regulates carbonic anhydrase activity in the chicken uterus by targeting CA2 during eggshell formation.
