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 participants; F—female; M—male; BMI—body mass index; WHR—waist-to-hip ratio; SBP—systolic blood pressure; DBP—diastolic blood pressure; MAP—mean arterial pressure; hsCRP—high-sensitivity C reactive protein. * p < 0.05 LS vs. HS (Paired t-test).
