(Shown are adjusted hazard ratios for the primary end point within specific subgroups. Squares denote hazard ratios; horizontal lines represent 95% confidence intervals. Hazard ratios indicate the relative risk in both intervention groups merged together (vs. the control group) within each stratum. Hazard ratios were stratified according to recruiting center and were adjusted for sex, age (continuous vari- able), family history of premature coronary heart disease (CHD) (yes or no), smoking (never smoked, former smoker, or current smok- er), body-mass index (BMI) (continuous variable), waist-to-height ratio (continuous variable), hypertension at baseline (yes or no), dys- lipidemia at baseline (yes or no), and diabetes at baseline (yes or no). Scores for adherence to the Mediterranean diet range from 0 to 14, with higher scores indicating greater adherence.)

Refer to the BMI subgroup:

A.) There are three hazard ratios, HR=0.69, HR=1.04 and HR=0.51; indicate and justify whether each hazard ratio is statistically significant or not.

B.) Interpret only the hazard ratio(s) which is (are) statistically significant in the context of this figure.
