The incidence of sensorineural hearing loss diagnoses in people with and without Alzheimer's disease - a nationwide cohort study.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSensorineural hearing loss (SNHL) is a risk factor for cognitive impairment, but little is known on whether the diagnosis of Alzheimer's disease (AD) affects the diagnosis of SNHL. We studied the temporal changes in the incidence of SNHL diagnosis in relation to AD diagnosis.
methodsThis study is part of Medicine use and Alzheimer's disease cohort (MEDALZ) study. Our nationwide register-based study included 42,934 community-dwelling persons who received a clinically verified AD diagnosis in 2008-2011 in Finland and a 1:1 matched comparison cohort. We calculated the incidence of SNHL diagnoses per 100 person-years (PY) from ten years before to five years after the date of AD diagnosis (index date).
resultsBefore the index date, the incidence of SNHL diagnoses was higher among persons with AD (1.51/100 PY) than in the comparison cohort (1.34/100 PY, adjusted hazard ratio, 95%Cl 1.10, 1.06-1.13). After AD diagnosis the incidence was lower among persons with AD (1.05 and 1.66/100 PY, adjusted hazard ratio, 95%Cl 0.60, 0.56-0.62). The incidence increased in a similar manner in both groups before the AD diagnosis. In the AD group the incidence peaked at the index date, but steeply declined shortly after, while in the comparison cohort, it continued its previous ascending course.
conclusionsThe incidence of SNHL diagnosis declines after AD diagnosis, suggesting that AD may alter diagnostic trajectories and access to audiological care.
