Table 4 Correlations between 24 h-CASP, 24 h brachial SBP or 24 h-CPP and covariates in all participants (n = 715)

From: 24-hour central aortic systolic pressure and 24-hour central pulse pressure are related to diabetic complications in type 1 diabetes – a cross-sectional study

  1. r-values are Pearson’s coefficients.
  2. MAP: mean arterial pressure, UAER: urinary albumin excretion rate, eGFR: estimated glomerular filtration rate.
  3. * Since SBP is included in MAP.
