SNORES Classification: Multicenter Prospective Validation for Obstructive Sleep Apnea.
Article in The Laryngoscope, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo validate a clinically feasible, multidimensional classification system-SNORES (Severity of apnea-hypopnea index, Nasal airflow limitation, Oxygen desaturation burden, Respiratory effort, Awake Endoscopic anatomy, and Sleep position dependency)-for obstructive sleep apnea (OSA), and to evaluate its ability to predict therapy escalation, CPAP adherence, and surgical intervention beyond the apnea-hypopnea index (AHI) alone.
methodsIn this prospective multicenter cohort study, 1560 adults with newly diagnosed OSA confirmed by in-laboratory polysomnography were enrolled. Each SNORES domain was scored from 0 to 3 using predefined objective criteria derived from routine diagnostic testing. Primary outcomes were therapy escalation, CPAP adherence, and surgical intervention. Predictive performance was compared with AHI alone.
resultsHigher SNORES scores were independently associated with therapy escalation (hazard ratio [HR] 3.10, 95% CI 2.62-3.67; p < 0.001) and surgical intervention (HR 2.71, 95% CI 2.21-3.33; p < 0.001). The SNORES framework demonstrated superior discrimination for therapy escalation (area under the curve [AUC] 0.82, 95% CI 0.78-0.86) compared with AHI alone (AUC 0.52, 95% CI 0.46-0.57; ΔAUC +0.30, p < 0.001). Removal of individual domains-particularly oxygen desaturation or respiratory effort-meaningfully attenuated predictive performance (ΔAUC -0.09 to -0.11).
conclusionSNORES is a feasible, reproducible, multidimensional framework that captures clinically relevant heterogeneity in OSA and guides individualized therapy more effectively than traditional AHI-only models. LEVEL OF EVIDENCE: 1:
