Ear Hygiene Practices, Ear Morbidity Amidst Environmental Noise in Urban Slums: Evidence to Recommend Comprehensive Ear Care Under Ayushman Arogya Mandirs in Eastern India.
Article in Journal of primary care & community health. 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
BackgroundEnvironmental noise is an under-recognised public health hazard in rapidly urbanising low- and middle-income countries. Urban slum residents are disproportionately exposed to chronic transportation and occupational noise, yet community-level evidence linking noise exposure with ear morbidity remains limited in India.ObjectivesTo assess the association between environmental noise exposure and ear morbidity in urban slums of Bhubaneswar, Odisha. To examine behavioural and socio-environmental determinants of ear health among the sample for associations to offer recommendations.MethodsThe study design is a community-based, stratified, cross-sectional study conducted in the urban slums of Bhubaneswar, Odisha, India, stratified into low-, medium-, and high-noise zones. The study population were 384 residents aged 10-50 years selected through stratified random sampling with proportional allocation. The noise stratification is generalised, on the basis of city administrative definitions.Data were collected using a semi-structured questionnaire that assessed socio-demographics, occupational exposure, ear hygiene, and health-seeking behaviour. Clinical ear examination, otoscopy and tuning fork tests were conducted. Logistic limitations did not permit performing pure tone audiometry. Ear health outcomes included normal, ear infection, at risk hearing loss or both. Associations were analysed using the chi-square test and multivariable logistic regression, with statistical significance at p<0.05.ResultsAmong 384 participants, the overall prevalence of ear morbidity was 21.1% (95% CI: 17.2-25.4), including ear infections at 11.2% (95% CI: 8.3-14.8), at-risk hearing loss at 2.6% (95% CI: 1.3-4.8), and combined infection with hearing loss at 7.3% (95% CI: 5.0-10.3). A graded increase in hearing loss risk was observed across noise exposure zones-2.4% in low, 10.9% in medium, and 15.6% in high noise areas (χ
