Interplay Between Rhinosinusitis and Eustachian Tube Dysfunction in Patients Undergoing Functional Endoscopic Sinus Surgery.
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 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 evaluate the association between chronic rhinosinusitis (CRS) and Eustachian tube dysfunction (ETD) using subjective and objective measures, and the relationship between disease laterality and Eustachian tube function (ETF). STUDY
designProspective cohort study.
settingSingle tertiary medical institution.
methodsEighty-five CRS patients who were candidates for FESS underwent comprehensive evaluation. Subjective assessments utilized the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) and Sino-Nasal Outcome Test-22 (SNOT-22). Objective evaluations comprised a 9-step inflation-deflation tympanometric test scored by maximal peak pressure difference (MPD), nasal endoscopy using the modified Lund-Kennedy (MLK) system, sinus CT scored via the Lund-Mackay (LM) system, and acoustic rhinometry measuring the second minimal cross-sectional area (MCA
resultsPoor ETF (ETDQ-7 ≥ 14) occurred in 36.5% of patients and was associated with higher SNOT-22 (median 48.0 vs 31.5, P < .001). ETDQ-7 correlated moderately with SNOT-22 total (r = 0.65). No significant differences in MPD, MLK, LM, or MCA
conclusionIn CRS, sinonasal symptom burden shows only a moderate association with patient-reported ETD. Higher ETDQ-7 scores often parallel greater SNOT-22 severity, suggesting that PROMs may help identify patients in whom ETD symptoms are partly influenced by CRS.
