Cardiovascular mortality	10	6,396	689	4.05 (2.53, 6.84)	0.75 (0.67, 0.81)	0.60 (0.53, 0.66)	1.87 (1.52, 2.30)	0.42 (0.30, 0.58)
Cardiovascular events	6	1,463	425	7.02 (2.21, 22.33)	0.80 (0.65, 0.89)	0.64 (0.49, 0.76)	2.21 (1.48, 3.30)	0.32 (0.17, 0.58)

CI, confidence interval; OR, odds ratio; PLR, positive likelihood ratio; NLR, negative likelihood ratio.
