Synergistic Effects of Environmental Noise and Aging on Hearing Loss: A Comparative Analysis of Elderly Residents Near Powerloom Industries.
Article in Indian journal of occupational and environmental medicine. 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
Context: Noise-induced hearing loss (NIHL) is a preventable yet understudied issue in nonoccupational settings, particularly among elderly populations near industrial areas, where chronic noise may worsen age-related hearing decline. Aim: This study aimed to evaluate the effects of powerloom noise on hearing health in elderly residents near industrial zones compared to those in quieter areas and to explore its interaction with ageing and health factors. Settings and Design: This cross-sectional, comparative study was conducted in a residential areas near powerloom industries and in quieter control areas within the same region. Methods and Material: A study was conducted from May to July 2024 with 436 participants aged above 60 years (218 near powerlooms, 218 in control areas), selected via stratified random sampling. Noise levels were measured using calibrated sound meters at residences, and hearing was assessed with a validated mobile application. Structured interviews collected demographic, health, and lifestyle data. Statistical Analysis Used: Statistical analysis includes regression, Results: Elderly residents near powerlooms had significantly worse hearing than the control group, with severity increasing with exposure duration. Ageing-related decline was steeper, worsened by diabetes and smoking. Noise above safe limits led to higher moderate-to-severe hearing loss. Statistical models confirmed noise as a key factor, highlighting the vulnerability of elderly populations and the need for protective measures. Conclusions: Chronic powerloom noise worsens hearing loss in elderly residents, amplifying age-related decline and health risks.
