The main effect of pulse rate was highly significant ( F (2,20) = 99.3, P < 0.001) and that of duration was marginally significant ( F (1,10) = 4.76, P = 0.054).

A combined (group × rate × polarity) ANOVA revealed a borderline significant interaction between group and polarity ( F (1,6) = 5.91; P = 0.051), providing some evidence that the threshold difference between fixed and alternating polarity was larger for ABI users than for CI users.
