Protocol for a cluster randomised controlled trial comparing structured Follow-up And Monitoring Of new USers of NHS hearing aids to usual care: the FAMOUS trial.
Article in Trials, 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 is a prevalent condition that impacts on social, mental and physical health, and has a significant economic burden. Hearing aids can improve the quality of life for those living with hearing loss; however, low and inconsistent use remains common. Within the National Health Service (NHS), follow-up care for new hearing aid users is highly variable and often lacks structure, which may contribute to low use. The FAMOUS trial investigates whether a structured care model for follow-up, combined with evidence-based behaviour change interventions, improves hearing aid use compared to usual care.
methodsFAMOUS is a multi-centre, two-arm parallel-group cluster randomised controlled trial (CRCT) with integral internal pilot, economic, and process evaluations. The trial involves 36 NHS audiology services and compares two types of follow-up for new adult hearing aid users: structured care, which includes personalised action plans, early monitoring, and routine follow-up at 6 weeks post-fitting, to usual care, which includes the offer of a follow-up 6-12 weeks after fitting. Recruitment is conducted through participating services over 3 months, with pseudo-anonymised routine data collected from electronic medical records of all patients who attend. Consent and outcomes are then collected from patients at 12 weeks post-fitting. For patients who provide consent to future contact, the primary outcome (self-reported daily hearing aid use) is collected at 12 months post-fitting. Secondary outcomes (quality-of-life (QoL), hearing-related disability, and economic measures) are collected at both timepoints. Qualitative interviews with a subset of patients and hearing professionals in the intervention arm will assess the acceptability and implementation of the intervention. Statistical analyses, including mixed-effects regression modelling, will be conducted under an intention-to-treat framework. DISCUSSION: FAMOUS addresses a critical evidence gap regarding the potential benefits of follow-up care for new hearing aid users. If the intervention is successful, it can be rolled out nationally using existing facilities with limited impact on resources, identified in the economic analysis, and would improve hearing aid use and quality of life for those living with hearing loss.
