SD: standard deviation, DSBP: delta (maximum-minimum) systolic blood pressure, DDBP: delta diastolic blood pressure, SD: standard deviation, CVS/D/P: coefficient of variation of systolic blood pressure/diastolic blood pressure/arterial peripheral pulse, ARVS/D/P: average real variability of systolic/diastolic/arterial peripheral pulse, ND: nondiabetics, D: diabetics. Variables are presented as medians (interquartile range: percentile 25-percentile 75) and comparisons between ND vs. D were tested with the Mann–Whitney rank sum test.
