Investigating associations between hearing, cognition, and social isolation using the Hertfordshire Ageing Study.

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
Objectives: The aim of the study was to investigate whether hearing threshold separately predicts cognitive score and social isolation score 10 years later by using the Hertfordshire Ageing Study (HAS) data. Methods: The Hertfordshire Ageing Study (HAS) is a longitudinal cohort study that measures hearing via pure tone audiometry at two timepoints, and social isolation and cognition variables at the second timepoint. Linear regression was implemented for both objectives using an unadjusted model, a model controlling for age and gender, and a model controlling for all confounders (sociodemographic, lifestyle, and clinical characteristics) relating to the exposure and outcome variables. For interpretability, coefficients were expressed as the expected change in outcome per doubling of hearing threshold. Results: A total of 231 and 254 participants were included in the final analyses. Over 10 years, hearing thresholds worsened by an average of 10.5 dB. Higher hearing thresholds were associated with lower MMSE scores ( Conclusion: The lack of evidence of an association despite strong theoretical evidence may be due to selection bias within the overall cohort study and the sensitivity of the outcome measures used for social isolation and cognition.
