Average marginal effects (AME) reported and interpreted as: For one unit increase in X the probability of recalling study participation increases by AME.

Interpretive Example: For each day of hypoxemia, the probability of recall of study participation decreased by 9.8%.

Alternatively, having a high school diploma increased the probability of recall of study participation by 17%.
