Table 2. Correlation with age for SardiNIA microvascular traits.
| Microvascular trait, Thick | Pearson | p-values adjusted |
|---|---|---|
| Number of bifurcation points (j2) | -0.318 | 1.8E-53 |
| Number of terminal points (j1) | -0.293 | 2.1E-45 |
| Total squared curvature (t5) | -0.144 | 3.7E-11 |
| Scale 3 fractal (f3) | -0.133 | 1.3E-09 |
| Total curvature normalized (t11) | 0.006 | 8.6E-01 |
| Ratio for arc length (t15) | 0.033 | 1.9E-01 |
The four most correlated traits shown in Fig 1A and 1B and two traits unaffected by age. The full names for tortuosity traits: total squared curvature (t5), total curvature divided over the chord length (t11), and interpolated arc length divided by original arc length (t15). Gender: males and females combined.
