24-hour Ambulatory Blood Pressure measurements were taken according to Standard Joint National Committee VII Guidelines / ESC and ESH Guidelines at each follow-up visit. In the 24-hour blood pressure monitoring, the blood pressure of patient was measured every 30 minutes during the daytime and every 60 minutes during the night time. When using ABP, it was ensured that at least two measurements per hour are taken during the person's usual waking hours and 1 measurement per hour are taken during the person's usual night time hours. The average value of at least 14 measurements taken during the person's usual waking hours and average of at least 8 measurements taken during the person's usual sleeping hours were used for calculation of mean value.

Baseline characteristics

Among the 353 subjects who were screened initially, 66 subjects did not receive the renal artery ablation procedure, 11 subjects received procedure but did not satisfy the definition of any arm. The 11 subjects who received RND procedure were followed up for exploratory analysis and considered as "unassigned arm". Of these subjects, 5 subjects completed the study, 6 subjects were withdrawn prior to study completion. Hence they were excluded during the endpoint and safety analyses.
