For study population of 2889 men and 3803 women with at least one year of follow-up.
Time ratio <1.0 indicates acceleration of time to the cardiac event or shortening of event free survival time.
For study population of 2645 men and 3400 women with a complete follow-up. Hosmer-Lemeshow chi-square of 11.0 in men and 6.7 in women indicated appropriate logistic models.
A multivariable adjusted attributable fraction which is directly calculated from individuals’ data using logistic regression and considers an average of all possible sequences for removal of risk factors in the community.
