highly significantp = 0.0058
ISCEV standard LA single flash (3 cd s m −2 , 2 Hz) analysis revealed a highly significant group effect for the b-wave amplitude [ F (1, 36.1) = 8.59, p = 0.0058] whereas age [ F (1, 30.3) = 1.23, p = 0.2764], eye [ F (1, 31) = 0.01, p = 0.9253], iris index [ F (1,50.5) = 0.25, p = 0.6177], and electrode distance [ F (1, 48.8) = 1.25, p = 0.2691] had no effect.
