Linear and Complex Measures of Heart Rate Variability during Exposure to Traffic Noise in Healthy Women

Figure 5

The boxplots illustrate the values of chaotic forward parameters one to seven (CFP1 to CFP7) for control (a) and traffic noise exposure (b) subjects with 500 RR intervals throughout. The point closest to the zero is the minimum and the point farthest away is the maximum. The boundary of the box closest to zero indicates the 25th percentile, a line within the box marks the median (not the mean), and the boundary of the box farthest from zero indicates the 75th percentile. The difference between these points is the interquartile range (IQR). Whiskers (or error bars) above and below the box indicate the 90th and 10th percentiles, respectively.
