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
backgroundDrug-induced sleep endoscopy (DISE) enables direct visualization of upper airway collapse patterns in obstructive sleep apnea (OSA) patients, but inconsistencies in sedative selection, monitoring methods, and administration techniques may affect result reproducibility. This meta-analysis evaluates how these factors influence complete collapse rates according to VOTE classification.
methodsSystematic searches of PubMed, Embase, and Cochrane Library identified studies performing DISE in OSA patients using single sedative agents (propofol, dexmedetomidine, or midazolam) with VOTE classification outcomes. Pooled collapse rates were estimated using generalized linear mixed models (GLMMs) with logit transformation. Univariate and multivariate metaregression analyses explored associations between sedative type, bispectral index (BIS) monitoring, drug administration method, body mass index (BMI), and collapse patterns.
resultsTwenty-two studies involving 3478 patients were included. Pooled complete collapse rates were velum 73.7% (95% CI 66.3-80.0), tongue base 40.6% (32.3-49.5), oropharynx 30.6% (24.6-38.4), and epiglottis 24.7% (17.3-34.0). Sedative type showed no significant association with collapse rates at any site (all PQM > 0.05). BIS monitoring was independently associated with reduced tongue base collapse (coefficient = - 1.39, p = 0.002), while BMI significantly predicted velum collapse (coefficient = 0.40, p < 0.001). Continuous infusion showed borderline significance at the oropharynx (P
conclusionsDISE outcomes are more influenced by sedation depth monitoring and patient anatomy than sedative choice. BIS monitoring should be prioritized for tongue base assessment, while BMI-driven velum collapse reflects anatomical factors. Standardized protocols emphasizing objective monitoring may enhance DISE reliability.
