subsample has at least three follow‐up assessments, and a “non‐response analysis” indicated that individuals who did not return for follow‐ups were younger, but no significant differences regarding other key characteristics have been observed. We continue to take measures to ensure minimal impact of “missing data” on our study's findings. There is notable diversity in age (ranging from 7 to 97), gender (52% female), self‐reported race and ethnicity (28% Black, 9% Hispanic). These data are available to the research community through several mechanisms, including directly through the NIAAA, through dbGAP, and in collaborations (see 1. Overview). In this review, we detail COGA's data collection methods for the specific brain function measures assessed, showcase their utility, significance and contributions to our understanding of AUD and related disorders, and highlight COGA research findings.
