The data are presented as mean ± SEM (standard error of the mean). P-values are calculated from t-test comparing case and control groups within population.
Case, centenarian; Control: individuals from general population; m/f, male/female; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure.
