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
Objective: The objective of this study was to investigate whether long noncoding RNA Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1) contributes to laryngocarcinoma development via regulating the Yes-associated protein 1- (YAP1-) mediated epithelial-mesenchymal transition (EMT) and the underlying mechanism. Methods: The effects of MALAT1 suppression and BET inhibitor JQ1 on the malignant phenotypes and cancer stem cell- (CSC-) like properties of laryngocarcinoma cells as well as the expression of bromodomain-containing protein 4 (BRD4), YAP1, and EMT markers were investigated. Moreover, the relationships between MALAT1 and miR-708-5p as well as between miR-708-5p and BRD4 were explored. Furthermore, whether MALAT1 regulated the malignant phenotypes of laryngocarcinoma cells via sponging miR-708-5p to target BRD4 was revealed by both Results: MALAT1 suppression inhibited the malignant phenotypes of laryngocarcinoma cells, such as decreased proliferation, promoted apoptosis, suppressed migration, and inhibited the CSC properties. Suppression of MALAT1 increased miR-708-5p expression and decreased the expression of BRD4 and YAP1 and inhibited EMT. Moreover, there were target relationships between MALAT1 and miR-708-5p as well as between miR-708-5p and BRD4. miR-708-5p overexpression and MALAT1 suppression had synergistic inhibitory effects on the malignant phenotypes of laryngocarcinoma cells and the expression of BRD4, YAP1, and EMT. Furthermore, Conclusions: Our results indicate that suppression of MALAT1 may inhibit laryngocarcinoma development by sponging miR-708-5p/BRD4 to regulate YAP1-mediated EMT. Targeting MALAT1/miR-708-5p/BRD4 axis may provide a promising therapeutic strategy for laryngocarcinoma.
