IADL impaired (ref = no)	0.97		2.63 (1.26–5.32)	0.01	10
ADL impaired (ref = no)	0.24		1.27 (0.76–2.05)	0.35	2

Fair-poor vision (ref = good to excellent)	0.17		1.18 (0.88–1.57)	0.26	2
Total					59

The riskindex score was obtained by multiplying each β coefficient by 1 ÷ 0.10 and then calculating the column total.
