HAART: highly active antiretroviral therapy; SDNN: standard deviation of all NN intervals; pNN50: the proportion derived by a division of the number of pairs of adjacent NN intervals differing by more than 50 ms in the entire recording by the total number of all NN intervals; r-MSSD, the square root of the mean of sum of the squares of differences between adjacent NN intervals; LF: low frequency; HF: high frequency. values for differences among the four categories applying F-test for continuous variables and or Chi-square for categorical variables. *Median (interquartile interval); diabetics ≠ controls, ; diabetics ≠ controls, ; naïve ≠ controls, ; diabetics ≠ controls, ; naïve ≠ controls, ; diabetics ≠ controls, ; naïve ≠ controls, ; diabetics ≠ controls, . |
