Not shown as not having a meaningful interpretation.

Estimate ± SE refer to the difference of the response between the reported level of this categorical predictor and the reference category of the same predictor.

These predictors were dummy coded, with the “IOI Type (1),” “Sex (Female),” “Age Cohort (Adult),” and “DP TYPE (DP2)” being the reference categories.
