24 h, day-time and night-time ambulatory BP parameters, entire group of 68
no effect
Not recorded as a finding: sentence says quercetin and placebo supplements did not significantly affect the parameters, which is not a two-sided between-arm statement and lists several endpoints
In the entire study group (n 68), quercetin and placebo supplements did not significantly affect mean 24 h, day-time and night-time ABP parameters (SBP, DBP, MAP, nocturnal dip in SBP and DBP).
