Hearing Impairments in People With Intellectual Disabilities: A Prospective Cohort Study on Prevalence and Healthcare Utilization.

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
backgroundPeople with intellectual disabilities (ID, prevalence ca. 1.04%) have an elevated risk of hearing impairments, which, if untreated, can hinder communication, cognitive development, and social participation. In a project called "HörGeist," we studied the prevalence of hearing impairments and the feasibility and utility of an outreach auditory screening, diagnosis, and intervention program for people with ID in their living and working environments.
methodsIn an age-stratified cohort study with a total of 1194 subjects, 1053 people with ID (outreach cohort, aged 1–90 years) underwent auditory screening in their living or working environment twice one year apart, and, if indicated, a diagnostic evaluation for a hearing impairment and either an intervention or a referral for outside treatment. To compare utilization, a control cohort of people with ID (141 subjects) was offered screening and auditory diagnostic testing in a clinical setting.
resultsClinically relevant hearing impairments were diagnosed in 44.0% of patients in the outreach cohort; 69.8% of these impairments had not been identified previously. Cerumen obturans affecting hearing was present in 9.9% of the impairments. Approximately one-third of the subjects or their carers overestimated their hearing ability. Screening and diagnostic evaluation yielded a conclusive result in 96.7% of cases. Screening had an estimated 92.3% specificity (95% confidence interval: [89.6; 94.3]) and 96.4% sensitivity ([94.1; 97.8]). None of the subjects in the invited control cohort made use of the auditory screening program. The prevalence of hearing impairments varied depending on sex, age, and type of institution.
conclusionThe prevalence of hearing impairments in people with ID is high, and most cases are unrecognized. A comprehensive outreach program of auditory screening, diagnostic evaluation, and intervention for people with ID appears feasible and justified and would reach more of the affected persons than a simple invitation. It could improve their social participation as well.
