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
Cervical cancer is one of the most common cancers worldwide. Many studies have reported the involvement of various miRNAs in cervical cancer progression. Our study was centered at investigating how let-7c-5p affected cervical cancer migration and invasion by regulating cell adhesion and its molecular mechanism. Bioinformatics was used for the analysis on differentially expressed mRNAs in cervical cancer and the prediction of their upstream regulatory miRNAs. Immunohistochemistry was performed to assess the expression of CHD7 in cervical cancer tissue. qRT-PCR was performed for examining how much let-7c-5p and CHD7 were expressed. Dual-luciferase assay was performed to verify the regulatory relationship between CHD7 and let-7c-5p. The CCK-8 and transwell assays helped in detecting cell viability, invasion and migration. The ability by which cells adhered to each other was detected by employing cell adhesion assay. In addition, the expression levels of the proteins related to cell adhesion and CHD7 were detected by Western blot. A remarkable high expression-level of CHD7 was discovered in cervical cancer tissues and cells. The cell viability, migration and invasiveness could be suppressed by the knockdown of CHD7 which could also attenuate the expression of cell adhesion-related proteins. Bioinformatics analysis showed that CHD7 had an upstream regulatory gene, miRNA-let-7c-5p, which was markedly lowly expressed in cervical cancer tissues and cells. To validate the binding relationship between CHD7 and let-7c-5p, dual-luciferase assay was performed. Rescue experiments revealed that the cancer-inhibiting effect of let-7c-5p in cervical cancer could be reversed by overexpressed CHD7. let-7c-5p regulates cell adhesion and attenuates cervical cancer migration and invasiveness by targeting CHD7. It indicates that the involvement of let-7c-5p/CHD7 axis is of significance in cervical cancer progression, which opens up new possibilities for us to develop novel clinical treatments for cervical cancer.
