Estimated prevalence (%) of patients meeting the criteria for clinical hypertension stratified by stages of hypertension together with the corresponding mean age (years), median length of stay (days), median number of blood pressure observations according to European ESC/ESH and American ACC/AHA guidelines (Supplementary Table ST-1 online). Abbreviations: BP, blood pressure; IQR, interquartile range; LOS, length of stay.
