Model Cox and Snell R²: 0.129, concordance between observed and predicted value: 67.6%. ^a Cognitive score ranges from 0-27 points and a score of less than 24 is considered to indicate cognitive impairment. The scale is subdivided into three groups, 0-7 (severe cognitive impairment), 8-15 (moderate cognitive impairment) and 16-23 (mild cognitive impairment). Severe cognitive impairment is reference category.
