Measurement error and information bias are ubiquitous in epidemiology, yet directed acyclic graphs (DAGs) are infrequently used to represent them, in contrast with confounding and selection bias. This represents a missed opportunity to leverage the full utility of DAGs to depict associations between the variables we actually analyse in practice: empirically measured variables, which are necessarily measured with error. In this article, we focus on applying causal diagrams to depict the data-generating mechanisms that give rise to the data we analyse, including measurement error.

- The study investigates how military blast exposure impacts functional disability among veterans, using functional disability as a measure of quality of life.
- It involved 540 veterans, assessing their experiences with blast exposure, tinnitus, and hearing loss over 5 years through disability questionnaires.
- Findings indicated that veterans with blast exposure, especially those with tinnitus and hearing loss, had significantly higher odds of experiencing moderate to high functional disability, ultimately suggesting that these factors severely diminish their quality of life.
Importance: The risk of developing Parkinson disease (PD) after objective hearing loss is unknown. PD studies using self-reported hearing loss are insensitive, and objective data are lacking.
Objective: To examine the association of hearing loss with incident PD in US veterans and its effect modification by well-established prodromal conditions and hearing aids.

Objective: Examine associations between military blast exposures on hearing loss and self-reported hearing difficulties among Active-Duty Service Members (ADSM) and Veterans from the Noise Outcomes in Servicemembers Epidemiology (NOISE) study.
Study Design: Cross-sectional.
Setting: Multi-institutional tertiary referral centers.
Objective: To describe associations between a history of traumatic brain injury (TBI) and the severity of tinnitus-related functional impairment among a national, stratified random sample of veterans diagnosed with tinnitus by the Department of Veterans Affairs (VA) healthcare system.
Setting: A multimodal (mailed and internet) survey administered in 2018. Participants: VA healthcare-using veterans diagnosed with tinnitus; veterans with comorbid TBI diagnosis were oversampled.
