Fig 1.
Box plots for sdNN and LF/HF for five investigated age decades divided by gender.
The box plots show two selected HRV indices (A: sdNN (TD) and B: LF/HF (FD)) for the five investigated age decades (1: 25–34, 2: 35–44, 3: 45–54, 4: 55–64 and 5: 65–74 years) and divided into males (black cross-striped boxes) and females (white boxes). The boxes show the data between the 25th and 75 Percentile, the middle line represents the median.
Fig 2.
Box plots for fwrenyi4 and Hc3,3 for five investigated age decades divided by gender.
The box plots show two selected HRV indices (A: fwrenyi4 (SD) and B: Hc3,3 (CE)) for the five investigated age decades (1: 25–34, 2: 35–44, 3: 45–54, 4: 55–64 and 5: 65–74 years) and divided into males (black cross-striped boxes) and females (white boxes). The boxes show the data between the 25th and 75 Percentile, the middle line represents the median.
Fig 3.
Box plots for SD1 and SPPA_r_8 for five investigated age decades divided by gender.
The box plots show two selected HRV indices (A: SD1 (PPA) and B: SPPA_r_8 (SPPA)) for the five investigated age decades (1: 25–34, 2: 35–44, 3: 45–54, 4: 55–64 and 5: 65–74 years) and divided into males (black cross-striped boxes) and females (white boxes). The boxes show the data between the 25th and 75 Percentile, the middle line represents the median.
