Univariate Regression Statistics

KCN NRL
Cspot-max (D) vs. CCSdiff (dimensionless) P < 0.0001; R2 = 0.5882 P = 0.0080; R2 = 0.0451
Cspot-max (D) vs. distance of Pach-min to CCSmax P < 0.0001; R2 = 0.3737 P = 0.8011; R2 = 0.0004

CCSdiff = difference between maximum and minimum corneal contribution to stress; CCSmax = maximum zone of corneal contribution to stress; Cspot-max = maximum zone of tangential curvature; D = diopter; KCN = keratoconus; NRL = normal control; Pach-min = minimum zone of thickness.
