Effectiveness of Superior Laryngeal Nerve Block in Patients with Neurogenic Cough: A Prospective Cohort Study.
Article in Iranian journal of otorhinolaryngology, 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
Introduction: A study was undertaken to evaluate the role of superior laryngeal nerve block in management of neurogenic cough. Materials and Methods: A Prospective Cohort study was conducted on 30 patients of neurogenic cough in Government Medical College, Patiala, India from Jan 2024 to May 2025. Adult patients with unexplained cough > 8wks were included in the study and superior laryngeal nerve block with long acting steroid and local anaesthetic was given. All patients were monitored every two weeks for three months post superior laryngeal nerve block. Pre and post treatment cough severity index (CSI) were compared. Results: In our study of thirty patients, twenty five patients showed subjective symptomatic improvement. Normality of continuous data was assessed using the Shapiro Wilk test. For Intra comparison Paired t- test was used. The mean cough severity index (CSI) score decreased significantly from 24.533 ± 2.909 to 16.167 ± 2.365 post intervention with p value 0.001 which was found to be highly significant. Conclusion: SLN block is an effective alternative therapeutic option for patients of neurogenic cough in terms of efficacy, minimal invasiveness and safety.
