When you look at the Design 3, members exactly who died the initial 2 years away from pursue-up and those individuals was indeed latest cigarette smokers were omitted. The newest Cox proportional risk regression assumption was affirmed. Mathematical studies try performed utilising the SAS, version 9.cuatro (SAS Institute, Inc., Cary NC).

Dining table step 1 gifts the newest descriptive functions of your own full try and from the Bmi kinds. The entire indicate age are 81.step 3 ± cuatro.five years. sexy lithuanian women The latest suggest Body mass index is twenty-seven.5 ± 1.seven having professionals classified since the step 1.8% skinny, 31.8% normal pounds, 39.2% obese, 20.7% obesity category I, and you will eight.6% category II/morbid being obese.
