Abbreviations: y.o.=years old; N=total number of cases; M=men; W=women; SD=standard deviation; PON=paraoxonase; TEAC=trolox equivalent antioxidant capacity; MDA=malondialdehyde. Data underlined are the median (min-max) of the total number of cases. Data between round brackets are mean values±SD. a, b, c, d, and e indicate, respectively, young adults, adults, older adults, nonagenarians, and centenarians. The table shows the Pairwise comparisons between the different groups, i.e., a, b, c, d, and e stratified for gender. p-value≤0.05 is considered significant; ns=not significant.
