Aerobic Exercise versus Electronic Cigarette in Vascular Aging Process: First Histological Insight

Table 2

Comparison of the number of layers of elastic fibers between the e-cigarette (K2) exposure group and the combination of e-cigarette exposure and moderate-intensity aerobic physical exercise (K3).

Group		Number of layers of elastic fibers			value
			Median	Range (min–max)
K2	7		9.0	8.0-10.0	0.628
K3	6		9.0	8.0-9.0

Description: the Mann–Whitney test. K0: control group; K1: moderate-intensity physical exercise group; K2: group exposed to electronic cigarettes; K3: moderate-intensity physical exercise group and exposed to electronic cigarettes.
