SAP / RNFL correlation coefficients (ρ) by SAP test-point location. Correlations are estimated across both eyes of glaucoma patients with one eye Severe. Blue arcs within each sector plot represent the RNFL sectors expected to correspond with that test-point location in the visual field. RNFL clock-hour sectors: S = superior, N = nasal, I = inferior, T = temporal. Range of values is -0.080 to 0.854: all values less than or equal to zero are shown in black. P-values for each correlation coefficient are indicated as follows: * p < 0.05, ** p < 0.01, *** p < 0.001
