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
Ear canal mass lesions are very rare and can arise due to varied pathology ranging from simple polyp to severe malignancy. Common causes for ear canal mass formation includes aural polyp, cholesteatoma, bony exostosis and tumors. Clinical symptoms and treatment options vary depending on pathology. This study describes various ear canal mass lesions that were evaluated and treated at our tertiary care hospital. It is a retrospective study on cases of ear canal mass lesions who were treated over a period of 2 years from 2021 to 2023. Data collection included age, sex, clinical symptoms, audiometry/ imaging findings, diagnosis, surgery and biopsy report. Collected data were analysed and reported. This study included 12 patients, among them 7 were females and the remaining 5 were males. Their age group ranged from 10 years to 76 years. Common clinical symptoms included ear pain, discharge and hearing loss. Ear examination showed polypoidal lesion in 9 cases, verrucous lesion in 2 cases and irregular mass in one case. Audiometry showed conductive hearing loss in 7 cases, mixed loss in 4 cases and sensory neural loss in one case. HRCT showed localised lesion in 7 cases and mastoid involvement in 4 cases. Simple excision of localized lesion was done in 6 cases and mastoidectomy was done in 4 cases. Final biopsy was suggestive of inflammatory polyp in 5 cases and cholesteatoma in 2 cases. Other reported pathologies included Squamous cell carcinoma, papilloma, hemangioma and glomus tumor. Mass lesions in ear canal can be of varied aetiology and complete evaluation in the form of detailed history, pure tone audiometry, HRCT of temporal bone and biopsy of the lesion is essential for proper diagnosis and management.
