The results are presented as mean ± SD for all the parameters except ROS which is presented as median (25th; 75th percentile).
a P value <0.05 when >40 y group was compared with the overall group.
b P value <0.05 when >40 y group was compared with the group ≤30 y.
c P value <0.05 when >40 y group was compared with the group 31-40 y
d P value <0.05 when >40 y group was compared with the group <40 y.
