Lower scores for continuous variables correspond with lower cognition or impairment and higher scores correspond to higher cognition or impairment. See “Methods” section for explanation of what was tested in models A, B, and C.
Association between mortality risk and reported elder self-neglect occurs during the first year of follow-up.
Association between mortality risk and reported elder abuse occurs after the first year of follow-up.
Refers to the original cohort or the successive cohort of the Chicago Health and Aging Project (CHAP).
The incremental change refers to the unit increase in the score. The ranges for these scores appear in Table 1.
