Box plots of age-dependent healthy reference values for selected metrics in the foot. For each metric, the left plot shows the values at baseline (orange) and PORH (blue) and the right plot shows the % change (turquoise). Red lines indicate the median value, boxes indicate the 25th and 75th percentiles, and the black dotted lines indicate the range. Outliers are indicated by red crosses. A unit of 1 indicates a dimensionless metric. VAD vessel area density, VLD vessel length density.
