Addressing Selection Bias When Estimating Associations Between Physical and Cognitive Functioning in Older Adult Women
Results indicate that loss to follow-up in SWAN leads to underestimation of the relationship between gait speed and cognitive performance. The association is strongest among the most disadvantaged, who are also more likely to drop out. Accounting for differential loss-to-follow-up is critical for a more accurate characterization of the association between gait speed and cognitive performance.
