Prevalence and Associated Factors of Olfactory and Gustatory Loss in Patients With Nasal Septal Deviation.
Article in Clinical otolaryngology : official journal of ENT-UK ; official journal of Netherlands Society for Oto-Rhino-Laryngology & Cervico-Facial Surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis study aimed to evaluate the olfactory and gustatory functions of patients with nasal septal deviation (NSD) and identify the factors associated with olfactory loss (OL) and gustatory loss (GL). DESIGN AND
settingRetrospective data analysis of cohort group.
participantsTwo-hundred fourteen adult patients with NSD at a tertiary hospital.
main outcome measuresOlfactory and gustatory functions were assessed using the psychophysical olfactory and gustatory function tests. The association of various demographic and clinical factors, including age, sex, NSD type, allergic sensitization status, presence of concha bullosa (CB), total serum immunoglobulin E (IgE) level, blood eosinophil count, and acoustic rhinometry parameters, with OL and GL was analysed.
resultsAmong the patients, 20.6% (44/214) and 16.4% (35/213) had OL and GL, respectively. Patients with CB showed a significantly lower threshold, discrimination, and identification (TDI) score than those without CB (p = 0.012). Conversely, the TDI score did not differ according to age group, sex, NSD type, or allergic sensitization status. Blood eosinophil count was inversely correlated with the TDI score (p = 0.003), whereas nasal cavity volume, minimal cross-sectional area, and serum IgE level were not correlated with the TDI score. In the multivariable analysis, the presence of CB (p = 0.029, odds ratio [OR] = 2.281) and a blood eosinophil count ≥ 190 (p = 0.030, OR = 2.155) were identified as significant factors associated with OL. No factors were significantly associated with GL.
conclusionThe presence of CB and a high blood eosinophil count are significant predictors of OL in patients with NSD.
