Day-night difference of changes in mean arterial pressure and the awake/asleep ratio in three groups. a) There was no significant difference of changes of mean arterial pressure between day and night in vehicle group. However, both valsartan and combination treatments reduced mean blood pressure more in daytime than in nighttime; b) At baseline (C3), awake/asleep ratios in all groups were negative. The ratios in both valsartan and combination groups turned positive at the day T14 although the ratio in vehicle was still negative.
