Odds for severe cognitive impairment according to MHAS late life risk index score category

Risk
score		 Number *Cases,
N (%)		 OR (95% CI) p value
0–6 749 23 (3.1) 1 (ref) ~
7–12 774 32 (4.1) 1.36 (0.79–2.37) 0.27
13–18 646 45 (7.0) 2.36 (1.43–4.01) <0.01
19+ 721 136 (18.9) 7.34 (4.75–11.84) <0.01

Total does not sum to 3,002 because of missing values. Odds ratios estimated using a logistic regression model in which risk index score category is the independent variable and severe cognitive impairment (yes or no) was the dependent variable.
