Demographic and Clinical Characteristics of Benign Laryngeal Lesions: Insights from a Decade of Experience in a Tertiary Hospital.
Article in Nigerian medical journal : journal of the Nigeria Medical Association. 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: Benign laryngeal lesions, characterized by non-cancerous growths in the larynx, significantly impact voice quality and respiratory function. These lesions, which include vocal cord polyps, nodules, papillomas, and cysts, often result from factors such as vocal abuse, viral infections, and chronic inflammation. While studies on benign laryngeal lesions are well-documented globally, data specific to Northern Nigeria remains sparse. This study aims to analyze the demographics, clinical features, treatment modalities, and outcomes of benign laryngeal lesions over a decade in a tertiary otolaryngology center in Northern Nigeria. Methodology: A retrospective review of 176 cases of benign laryngeal lesions was conducted over 10-years (2011-2020). Data were collected on patient demographics, clinical presentation, risk factors, lesion characteristics, and treatment outcomes. All patients underwent flexible laryngoscopy, with a subset receiving CT scans and histopathological examination. The study excluded malignant lesions. Results: The study population comprised 123 males (69.9%) and 53 females (30.1%), with a male-to-female ratio of 2.3:1. The age range of patients was from 1.5 to 69 years, with a mean age of 34.74 years (±16.64). The most common presenting symptom was hoarseness (94.8%), and most lesions were vocal cord polyps (52.3%), followed by vocal cord nodules (34.7%) and juvenile-onset respiratory papilloma (6.8%). The glottic region was the most frequent site of lesion occurrence (94.9%). Treatment primarily involved voice rest (43.2%), direct laryngoscopy with excision (22.2%), and microlaryngeal surgery (8.0%). Treatment outcomes showed a cure rate of 40.9%, with a recurrence rate of 29.0%. Conclusion: This study provides valuable insights into the demographic and clinical profiles of patients with benign laryngeal lesions in Northern Nigeria. The findings indicate a predominance of vocal cord polyps, significant gender disparity, and the effectiveness of surgical interventions. These results align with regional and international data but highlight the need for more localized studies to better understand the epidemiology and management of these lesions in Northern Nigeria. Further research should explore specific risk factors and the longterm outcomes of different treatment modalities.
