Medications were uptitrated and hydrochlorothiazide was added according to protocol for 6 months. The primary endpoint was the office visit-to-visit SD of SBP. The secondary endpoints included average real variability (ARV), office SBP, and home SBP.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The losartan group (n = 71) and amlodipine group (n = 73) finished the scheduled visits between April 2013 and May 2017. The office visit-to-visit SD of SBP was comparable between the losartan and amlodipine groups (11.0 \u00b1 4.2 vs. 10.5 \u00b1 3.8, P = 0.468). The office visit-to-visit ARV of SBP was significantly elevated in the losartan group (10.6 \u00b1 4.3 vs. 9.1 \u00b1 3.4, P = 0.02). The absolute SBP decrement from baseline to 6 months was similar between groups, although the office mean SBP at 6 months was higher in the losartan group (132.3 \u00b1 12.9 vs. 127.5 \u00b1 9.0 mm Hg, P = 0.011). In home blood pressure analysis, evening day-to-day BPV indexes (SD and ARV) were significantly higher in the losartan group at 6 months.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The lowering effect of the office visit-to-visit SD of SBP was similar between losartan and amlodipine.
