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
Objective: Laryngeal dysplasia and Reinke's edema (RE) are common vocal fold lesions associated with smoking. While the former is cancer prone, most cases of the latter do not undergo malignant transformation. Therefore, we proposed identifying biomarkers of smoking-induced benign-malignant transformation of vocal fold lesions. Methods: Intraoperative vocal fold tissue specimens were collected from 12 smoking patients, including 4 cases of RE, 4 cases of high-risk dysplasia (HD), and 4 cases of laryngeal carcinoma (CA), and from 4 nonsmoking vocal fold polyps (VFP) patients. RE and HD were set as experimental groups, and CA and VFP were set as positive and negative control groups, respectively (for subsequent expression analysis of hub genes screened). RNA sequencing and DIA-MS were employed to screen for differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) in RE\HD. Venn analysis was used to identify co-expressed DEGs\DEPs. Functional enrichment analysis was performed to explore DEG\DEP-related pathways. LASSO regression and SVM-RFE algorithm were applied to screen for hub genes. The expression levels and prognosis of the hub genes were analyzed based on the TCGA database. The expression levels of the hub genes were further verified using RT-qPCR. Results: A total of 45 co-expressed DEGs\DEPs were identified in RE\HD, with significant enrichment observed in the HIF-1 signaling pathway. Three hub genes were identified: TMPRSS11B, SASH1, and TPRG1, which exhibited reduced expression and were associated with poor prognosis in head and neck squamous carcinomas. RT-qPCR analysis confirmed that the mRNA levels of TMPRSS11B were highly expressed in RE and low in HD compared to VFP. Conclusion: This study reveals that TMPRSS11B may be a potential biomarker of smoking-induced benign-malignant transformation of the vocal fold lesions, providing a predictive and therapeutic target for early diagnosis and treatment of laryngeal carcinoma.
