Hearing dynamics in patients with traumatic tympanic membrane perforation.
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. Cited by 1 paper.
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
backgroundHearing distortions from trauma to the ear could occur by direct perforation of the tympanic membrane.
aimTo characterize hearing thresholds in patients with traumatic tympanic membrane perforation and changes in hearing occurring in the course of treatment. STUDY
designProspective analytical study.
settingOlabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. METHODOLOGY: We prospectively entered in a proforma the demographics of 60 patients with traumatic tympanic membrane perforation at the teaching hospital in Sagamu, Nigeria over a period of five years as well as their hearing assessment with pure tone audiometry at initial contact and six weeks post-injury. The type of hearing loss, pure tone average and air-bone gaps were recorded. Hearing changes between initial and second audiometric assessments were analyzed and compared.
resultsThe data obtained from 60 patients with 73 traumatized ears were analyzed. In all, 64 (87.7%) of the ears had hearing loss while 33(45.2%) had conductive hearing loss. Injured ears had significantly worse hearing and higher air-bone gaps ABGs compared with non-traumatized ears. There was notable improvement in hearing thresholds and closure of air-bone gaps in the course of treatment, which was significantly more at the low frequencies compared with the high frequencies.
conclusionPatients with traumatic tympanic membrane perforation majorly had conductive hearing loss in the injured ears with audiometric confirmed air-bone gaps and increased hearing thresholds which were not frequency dependent. There was appreciable improvement in hearing parameters over time, significantly more at the low frequencies.
