Results

A strong correlation between the SBR and age was observed. The correlation coefficient in males and females were -0.566 and -0.502, respectively. The analysis of variance revealed that aging led to a decline of the SBR, and a significant difference (p?=?0.005) was observed among generations. Gender also affected the SBR, and there was a significant difference between males and females (p?=?0.036). The SBR in females was higher than in males. Consequently, the multiple comparison revealed a significant difference between 50s and 70s (p?=?0.015) and 50s and 80s (p?=?0.006).
