When verifying hypothesis 2.3, the ANCOVA for heart rate variability as a dependent variable showed a marginally significant effect for low vision accessibility features ( F ( 1 , 18 ) = 3.034 , p = 0.097 , η 2 = 0.026 , C o h e n ′ s F = 0.41 , p w r = 0.41 ), showing marginally lower HRV for websites with low vision accessibility enhancements ( M = 0.155 , S E = 0.124 ) than for websites without those adjustments ( M = 0.481 , S E = 0.124 ).
