To the Editor One of the most consistent findings in research on percentage flow-mediated dilation (FMD%) is the negative correlation between baseline arterial diameter (Dbase) and FMD% itself. The study by Namtvedt et al 1 is no exception in this respect. FMD% is obviously already an attempt to ‘normalise’ the measured change in arterial diameter (in millimetre) for variability in Dbase, but seems to do this job poorly.2 ,3
In a well-designed study, Namtvedt et al 1 reported that FMD% was 3.7% lower in patients with …
