Multi-omics analysis reveals the alterations in the tumor microbiome and metabolome associated with cervical cancer lymph node metastasis.

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
Lymph node metastasis (LNM) is the primary mode of cervical cancer (CC) metastasis and is associated with a poorer prognosis. A comprehensive understanding of the underlying mechanisms driving LNM is critical to improving CC patient outcomes. Previous studies have demonstrated that alterations in the intratumor microbiome contribute to tumor progression, with metabolic regulation as a key mechanism. This study aims to investigate the role of intratumor microbiota and tumor metabolism in CC LNM. The microbiome analysis revealed significant differences in the diversity and composition of the intratumor microbiome between CC with and without LNM. IMPORTANCE: This study comprehensively characterized the intratumor microbiota and tumor metabolism associated with lymph node metastasis (LNM) of cervical cancer (CC) by performing 16S ribosomal RNA sequencing, global untargeted metabolomics, and high-resolution spatial metabolomics on surgical CC specimens. Our findings revealed distinct compositions and diversities of intratumor microbiota between CC with and without LNM. Each group exhibited specific bacterial genera that could potentially serve as diagnostic tools for CC LNM, and
