Association Between Polypharmacy and Self-Reported Hearing Disability: An Observational Study Using ATC Classification and HHIE-S-It Questionnaire.
Article in Audiology research, 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
backgroundhearing loss represents, today, one of the most significant health problems affecting the world's population. This clinical condition, particularly manifest in adulthood, can arise or be aggravated by both the presence of specific pathologies and by taking multiple classes of drugs at the same time.
methodsto understand this relationship, the present non-interventional observational study aimed to investigate the relationship between worsening hearing abilities in 1651 patients aged between 18 and 99 years. In particular, the thorough history of patients allowed us to evaluate the pathological profiles, pharmacological profiles, and therapeutic regimens adopted. This allowed us to evaluate its association with self-reported hearing loss, assessed through the administration of the HHIE-S-It questionnaire. Furthermore, given the presence of multimorbidity, the possible correlation between self-reported hearing loss and the specific classes of drugs, categorized using the Anatomical Therapeutic Classification (ATC) system, was evaluated.
resultsthe results highlighted how patients taking drugs, both in mono- and polytherapy regimens, had higher hearing deficits than patients not taking drugs. Furthermore, an apparent dose-response effect, in which the risk of moderate to severe impairment progressively increased with the number of drugs taken, was also observed. Different classes of drugs, particularly those used for the treatment of diseases of the cardiovascular system, as well as drugs for acid-related disorders, were significantly linked to an increased risk of perceived hearing impairment. On the contrary, agents belonging to the antidiabetic category have proven to be drugs capable of offering a potential protective effect.
conclusionthis study highlighted how both the number of drugs taken and some specific categories of drugs can contribute to perceived hearing impairment. While this evidence highlights the importance of integrating audiological evaluation into the management of patients in polypharmacy, the cross-sectional nature of the design precludes the inference of causality. This evidence still favors safer and more personalized therapeutic strategies.
