Medical history variables were abstracted based on thorough review of the medical record by a nurse abstractor.
The most common cancer types were prostate cancer (N=251 men, 11.4% of men), breast cancer (N=172, 3.9%), melanoma (N=103, 2.3%), colon cancer (N=70, 1.6%), uterine cancer (N=48, 1.1%), and bladder cancer (N=47, 1.1%); other cancer types were present in < 1% of the sample. This excludes non-melanoma skin cancer.
N=46 (1.0%) possible diabetes, N=618 (14.1%) definite diabetes, N=10 with Type 1 diabetes, N=165 (3.7%) on insulin
Note. WAIS-R = Wechsler Adult Intelligence Scales-Revised. WMS-R = Wechsler Memory Scale-Revised. All participants completed the Auditory Verbal Learning Test (AVLT) as previously reported (Stricker et al., 2021). Subsamples reported here indicate slight variations in sample size by measure. 93% of participants in the original AVLT sample have all other measures listed here.
