Note. Positive B for ID-TD Status variable indicates the odds of having anxiety are greater for ID compared to TD. Negative B for family income indicates that the odds of having anxiety increase as family income decreases. Odds ratio indicates the percent greater likelihood of having anxiety for one status group over another (ID compared to TD if B is negative) and for each 1-level decrease in family income. For ease of interpretations, significant odds ratios where the odds are greater for ID compared to TD are bolded.
