Exact age linked to more accurate dementia risk predictions
Across three cohorts, age-and-sex models using exact age scored 0.71, 0.78 and 0.75 for prediction accuracy, higher than models using age groups.Across three cohorts, age-and-sex models using exact age scored 0.71, 0.78 and 0.75 for prediction accuracy, higher than models using age groups.
