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
backgroundThe objective of this study was to investigate the effect of mammalian-enabled protein (Mena) on invasion and metastasis of HPV16-related oral squamous cell carcinoma (OSCC) and the underlying mechanism. MATERIALS AND
methodsThe Mena gene expression profile of HPV-related OSCC was analyzed from the TCGA, GEO and TIMER databases. Immunohistochemistry was performed to study Mena, and the expression of invasion and metastasis-related markers and their clinicopathological characteristics. The role of Mena in the biological behavior of OSCC cell lines was assessed through both non-transfected and stably transfected models, analyzing EMT-related markers in vitro. The effect of Mena on HPV16-related OSCC metastasis through immunodeficient mouse model in vivo.
resultsMena expression was significantly decreased in HPV16-positive OSCC, and Mena expression in HPV16-negative OSCC was related with lymphatic metastasis and TNM stages, and E-cadherin, vimentin and MMP-2, but it was not statistically significant in HPV16-positive OSCC. Increased Mena expression was significantly correlated with a poor overall survival and disease-free survival in an HPV16-negative OSCC patient. Mena plays a vital role in promoting OSCC cell migration, invasion and metastasis.
conclusionsMena promotes OSCC invasion and metastasis in HPV-negative OSCC by activating the EMT process. However, Mena expression in OSCC infected with HPV16 is inhibited, thus suppressing its invasion and metastasis ability.
