Chronic suppurative otitis media and hearing loss among children in Eastern Greenland.
Article in International journal of circumpolar health, 2025. 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
Greenland has a high prevalence of chronic suppurative otitis media (CSOM), causing hearing loss (HL) in children. Understanding regional differences in prevalence is essential for public health service provision. This school-based cross-sectional study is the first to examine the prevalence of HL among children attending the only school in Tasiilaq, East Greenland. Video-otoscopy, tympanometry and pure-tone air and bone conduction audiometry were performed. In total 92 of 114 children aged 5-11 were included. 51 children (55%) had HL defined as pure-tone-average (PTA) >15 dB in the worst hearing ear according to the American-Speech-Language-Hearing-Association-criteria. Whereas 21 children (23%) had HL with PTA >20 in worst hearing ear according to the WHO-criteria. None of the children had previously been diagnosed. Among the 184 otoscopies, 45 were normal (24%), 43 showed wax-block (23%), 10 showed tympanic membrane perforation (5%) and 86 had other otitis media-related sequelae (47%). A high prevalence of HL and CSOM were found among children in East Greenland. 25% of the children should be assessed for hearing rehabilitation, indicating that HL on the east coast remains undiagnosed and untreated. The results highlight regional variation in CSOM and HL and support the need for regional data and new initiatives to prevent HL across Greenland.
