Data are presented as the mean ± standard deviation (SD) (normally distributed data) or median and interquartile range (non-normally distributed data). LS—low salt; HS—high-salt; N—number of subjects; F—female; M—male; TBARS—Thiobarbituric Acid Reactive Substances; FRAP—Ferric-Reducing Ability of Plasma; 8-iso-PGF2α—8-iso Prostaglandin F2α. * p < 0.001, † p < 0.001, ‡ p < 0.001 LS vs. HS (paired t-test).
