Prevalence and Patterns of Hearing Thresholds in Unilateral Hearing Loss: A Retrospective Analysis at the National Ear Care Centre, Kaduna.
Article in Journal of the West African College of Surgeons. 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: Unilateral hearing loss (UHL) is a prevalent audiological concern that can significantly impact an individual's quality of life. This retrospective study, conducted at the National Ear Care Centre, Kaduna, aimed to determine the hearing threshold pattern in a cohort of 693 patients with UHL, ranging in age from 5 to 70 years. Materials and Methods: Data collected between January 2018 and December 2022 included pure-tone audiometry results, patient demographics, and medical history. Audiometric assessments were conducted using an A2d diagnostic audiometer. Descriptive statistics and graphical representations were used to analyse the data and identify patterns in hearing thresholds at various frequencies. Results: The analysis revealed distinct hearing threshold patterns in patients with UHL. Notably, sensorineural hearing loss (SNHL) was the most prevalent type, with 68.05% of participants exhibiting this pattern. Conductive hearing loss and mixed hearing loss were observed in 19.32% and 12.63% of participants, respectively. The hearing threshold patterns varied between the right and left ears, suggesting the importance of considering laterality in clinical assessments. Conclusion: This study contributes valuable insights into the hearing threshold patterns in patients with UHL, encompassing a broad age range. The predominance of SNHL highlights the need for tailored diagnostic and management approaches. Understanding the audiometric characteristics of this population is essential for the development of patient-specific interventions and treatment strategies.
