Table 1 Associations of simple overall CNP measures vs death using images of excellent, good and fair quality (n = 132).
From: Spatial statistical modelling of capillary non-perfusion in the retina
Overall CNP index in images of excellent, good or fair quality (n = 132) | Automatic grading: Total percentage of CNP damaged pixels: One number for inner circle and one number for outer ring | ||
|---|---|---|---|
Continuous scale, % | p-value | ||
Inner circle | Survived | Mean = 19.8 SD = 4.3 | p = 0.73 (Logistic regression) p = 0.65 (2-sample t-test) |
Died | Mean = 20.2 SD = 2.8 | ||
Outer ring | Survived | Mean = 8.8 SD = 3.5 | p = 0.86 (Logistic regression) p = 0.88 (2-sample t-test) |
Died | Mean = 8.9 SD = 3.3 | ||
