Lymphocytes in EDTA blood before and 120 min after application of the experimental condition. Green dots represent the E-cig–, red dots represent the E-cig+, black dots represent the cig, and grey dots represent the IQOS. Statistical significances are given for IL-6 concentration in plasma before and 120 min after application of the experimental condition. Green dots represent the E-cig–, red dots represent the E-cig+, black dots represent the cig, and grey dots represent the IQOS. Statistical significances are given for Carbon monoxide concentration (CO) in the exhalation with a point cloud and the mean value before and 120 min after application of the test condition. (Pulse wave velocity (PWV) with values (mean ± SEM) before, directly after the use, and over time up to 60 min after application of the test condition. Green dots represent the E-cig–, red dots represent the E-cig+, black dots represent the cig, and grey dots represent the IQOS. Statistical significances are given for Augmentation index adjusted at heart rate of 75 bpm (AIx@75) with values (mean ± SEM) before, directly after, and over time up to 60 min after application of the test condition. Green dots represent the E-cig–, red dots represent the E-cig+, black dots represent the cig, and grey dots represent the IQOS.
