Olfactory-Related Quality of Life After Endoscopic Transsphenoidal Surgery.
Article in Laryngoscope investigative otolaryngology, 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
Background: To analyze olfactory-related quality of life (QOL), assess subjective and psychophysical olfactory dysfunction, and identify factors associated with changes in olfactory-related QOL following endoscopic endonasal transsphenoidal approach (EETSA). Methods: This study included 112 patients who underwent an EETSA between August 2019 and June 2022. Participants completed assessments before and after surgery, including the YSK Olfactory Function (YOF) test, the Questionnaire of Olfactory Disorders (QOD; comprising QOD-LQ, QOD-S, QOD-P, and QOD-VAS subscales, with higher scores indicating greater QOL impairment), the 36-Item Short-Form Survey (SF-36), and the 22-Item Sino-Nasal Outcome Test (SNOT-22). Clinical characteristics, intraoperative events, and postoperative complications were reviewed retrospectively. Results: Post-EETSA assessment revealed significant increases in mean QOD-LQ, QOD-P, and QOD-VAS scores, while neither physical health scores (SF-36 PCS) nor mental health scores (SF-36 MCS) showed significant changes following EETSA. Twenty-seven patients (24.1%) reported subjective olfactory dysfunction through SNOT-22 with normal YOF test results. "Decreased sense of smell" scores in SNOT-22 demonstrated significant positive correlations with QOD-LQ, QOD-P, and QOD-VAS scores. Female patients exhibited significantly greater deterioration in QOD-LQ and QOD-VAS than males, with female sex an independent factor for both. Postoperative CSF leakage ( Conclusions: Post-EETSA evaluation should emphasize both olfactory-related QOL and subjective olfactory dysfunction rather than focusing solely on psychophysical olfactory function. Comprehensive pre- and post-operative counseling addressing these aspects is essential for optimal patient care, with particular attention given to high-risk populations. Level of Evidence: 4.
