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
Currently, the impact of the microbiome on the progression and recurrence of esophageal cancer remains unclear. Microbes have been demonstrated to increase programmed death-ligand 1 (PD-L1) expression in certain epithelial tumors, thereby facilitating immune escape. Therefore, we hypothesized that the microbiome in esophageal tissues might be involved in the progression and recurrence of esophageal squamous cell carcinoma (ESCC) through PD-L1 upregulation. To assess this possibility, we analyzed the relationship between the microbial community composition and PD-L1 expression. We found that the microbiome of esophageal cancer tissue significantly differs from that of normal tissue, and Porphyromonas gingivalis and Fusobacterium nucleatum could represent markers of ESCC. An immunohistochemical assay revealed that P. gingivalis and F. nucleatum infection led to a significant increase in PD-L1 expression on the membrane surface of tumor cells, and this finding was further confirmed in cell experiments. Our findings suggest that eliminating intratumoral P. gingivalis and F. nucleatum infection could represent an important therapeutic strategy for reducing the progression and recurrence of esophageal cancer.
