Discussion SEPHAR was the ﬁrst study addressed to the prevalence, awareness, and control of hypertension on a representative sample for the entire population of Romania. Even if the selection of the subjects was based on the method of strat- iﬁed proportional sampling, the results must be cautiously interpreted due to the limited number of subjects included, in comparison with the adult inhabitants as a whole. When referring the data to the literature, we have to notice the heterogeneity of diﬀerent studies with regard to the sampling method (stratiﬁed sampling or selection
