approached significancep = 0.0595
Importantly, the test for the step function, once the other predictor is taken into account, still approached significance, despite the loss of one degree of freedom [ t (93) = 1.91, p = 0.0595], while that for the gradual increase predictor, after taking the other predictor into account, indicated a total absence of effect [ t (93) = 0.002, p =0.9985].
