Popis: Although we regret that Adiyaman et al1 misinterpreted some of our results, we are glad to see that they agree with the main findings of our study,2 in which we described a strong and previously undetected inverse association between ambulatory arterial stiffness index (AASI) and day-night blood pressure (BP) fall. Indeed, they were able to replicate our findings in 2 different cohorts.3,4 Adiyaman et al1 argue that the estimate of AASI may be influenced by the night:day ratio of the number of BP readings. However, to support their view, they rely on ambulatory BP recordings performed with a very low frequency of nocturnal BP readings. In fact, the night:day ratio of the number of BP readings in their study was only ≈0.30 with 26 to 30 measurements during the day and 8 to 9 measurements at night (see the figure in the letter by Adiyaman et al1) because of a longer nocturnal interval between automated measurements. In our representative patients (Figure 3 of our article),2 the number of valid …
