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
objectivesThis study aimed to investigate the effect of transfecting SOX2-shRNA vector lentivirus to SACC cell lines on the biological behavior of salivary adenoid cystic carcinoma (SACC)-LM and SACC-83.
methodsThree types of SOX2-shRNA lentiviral vectors (817, 818, and 819) were constructed and transfected successfully. The shRNA with the best inhibitory effect was screened out and transfected into SACC cells. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot were used to detect the expressions of Survivin, E-cadherin, and N-cadherin of SACC-LM and SACC-83. CCK-8 and flow cytometry were used to detect SACC-LM and SACC-83 proliferation and apoptosis. Cell scratch test and Transwell method were used to detect the migration and invasion capabilities of SACC-LM and SACC-83.
resultsSOX2-shRNA-819 had the best interference effect among the three lentiviruses. After transfecting SOX2-shRNA-819 into SACC-LM and SACC-83, the expressions of SOX2, Survivin, and N-cadherin were significantly reduced, and that of E-cadherin was significantly increased (
conclusionsshRNA interference technology reduced SOX2 expression while downregulating Survivin expression. These two expressions may be related. Low SOX2 expression inhibits the proliferation, migration, and invasion of SACC cells and promotes the apoptosis of SACC cells. SOX2 may be involved in the epithelial⁃mesenchymal transition process. This study provided a relevant theoretical basis for targeting SOX2 gene therapy in SACC.
