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
purposeThe study aimed to evaluate the long-term efficacy and safety of superior laryngeal nerve (SLN) block for treating chronic neurogenic cough (CNC) in a large patient cohort.
methodsA retrospective review was conducted on patients treated between January 2019 and October 2023. Data collected included patient demographics, number of injections, follow-up times, subjective cough severity, and Leicester Cough Questionnaire (LCQ) scores.
resultsAmong 117 patients (76.1% female; mean age 66.1), the median number of injections was 3, with a median follow-up duration of 4 weeks. Subjective improvement was reported in 74.4% of cases, with mild adverse events occurring in 8.4% of injections. Regression analysis showed a strong correlation between decreased subjective severity and time. LCQ scores improved slightly within 1-3 months and 25-40 months.
conclusionThe findings suggest that SLN blocks effectively reduce subjective severity and improve LCQ scores long-term, with sequential injections potentially reducing chronic steroid use risks. Further prospective studies are recommended to optimize dosing intervals.
