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
The metastasis and recurrence of nasopharyngeal carcinoma (NPC) contribute to the poor prognosis of patients. Inhibiting epithelial-mesenchymal transition (EMT) is an effective strategy to obstruct metastasis. Therefore, this study aimed to explore the effects of Capn4 on the EMT of NPC cells and its specific mechanism of action. The mRNA and protein expression levels of objective genes in NPC cell lines (5-8F and CNE-2) were evaluated by qRT-PCR and western blotting methods. The subcellular localization of Capn4 was detected by immunofluorescence (IF). Migration and invasion abilities of NPC cells were examined via wound-healing and trans-well methods, and the linkage between Snail and its downstream effector gene (claudin-11) was validated by chromatin immunoprecipitation (ChIP), dual-luciferase, and the yeast one-hybrid assays in series. Over-expression of Capn4 activated the PI3K/AKT signaling pathway and improved the expression of Snail, thus promoting the migration and invasion abilities of NPC cells. Mechanically, claudin-11 is one of the target genes in NPC cells that Snail regulates in a transcriptional regulatory manner. By blocking the regulatory axis of CAPN4/AKT/Snail/claudin-11 can significantly inhibit the invasion and metastasis of NPC cells. Capn4 promoted the EMT of NPC cells by activating the PI3K/AKT/Snail/claudin-11 axis, thereby promoting the malignant development of NPC. The Capn4/PI3K/AKT/Snail/claudin-11 axis might be a novel target to prevent NPC progression.
