Table 4 AUC data

From: Retinal vessel diameters and reactivity in diabetes mellitus and/or cardiovascular disease

  DM (n = 36) CVD (n = 43) DM and CVD (n = 37) p value
AUCBaseline data −0.9 (2.0) −1.4 (2.2) −1.0 (3.1) 0.704
AUC20 s Flicker 14.9 (6.0–30.1) 19.8 (−0.7–37.8) 12.0 (1.1–24.7) 0.429
AUC20 s Constriction −4.0 (−15.7 to 3.8)* −14.4 (−27.5 to −3.4) −10.1 (−20.0 to −3.7) 0.038
AUCLast 30 s −3.5 (18.9) −6.7 (26.0) −7.3 (23.1) 0.748
  1. All data are presented as either means (± standard deviation) or median (upper quartile/lower quartile). Statistical significance is shown by bolded p-values. All values given in percentage change to baseline vessel diameters or times in seconds
  2. AUC baseline area under the curve of the averaged 30 s prior to flicker start, AUC 20 s FL area under the curve of the averaged profile during 20 s flicker, AUC 20s Constriction area under the curve of 20 s duration 10 s following flicker cessation, AUC Last 30s area under the curve of the last 30 s of the averaged reation profile
  3. p value by analysis of variance or the Kruskal–Wallis test
  4. * p < 0.05 lower than the two other groups
