A study is run to evaluate risk factors for incidence hypertension. All participants are free of hypertension at the start of the study and are followed for 4 years, at which time they are reassessed for hypertension. Risk factos are measured in all participants at the start of the study. A total of n=3182 participants enroll and 1123 develop hypertension over 4 years. A multiple logistic regression model is run and the results are shown:
*Gender is coded 1 = male and 0 = female. Current smoker is coded 1 = yes and 0 = no.
a. What is the relative importance (statistical significance) of the risk factors? Justify your answer.
b. Estimate adjusted odds ratios to quantify the effect of gender and current smoking status on incident hypertension.
c. Who is more likely to develop hypertenion, a man or a woman? Justify your answer.
