Predictors of receiving therapy among very low birth weight 2-year olds eligible for Part C early intervention in Wisconsin

Table 2 Unadjusted and adjusted odds ratios (95% confidence interval) of receiving therapy for a sample of very low birth weight children (n=176), who, at age 2, meet Wisconsin state eligibility criteria ^A for early intervention due to developmental delay

^A Wisconsin state eligibility criteria for early intervention due to developmental delay is determined by performance on a standardized developmental evaluation that is more than 1.5 standard deviations from the mean.
^B Neighborhood disadvantage categories were created from an overall neighborhood disadvantage index (combining maternal education, poverty, single-family households, maternal unemployment, and incomes below state median each collected at the Census tract level; higher scores indicate more disadvantage) to correspond to disadvantaged (highest tertile), moderate disadvantaged (middle tertile), and advantaged (lowest tertile) and modeled as an ordinal variable. The odds ratio can be interpreted as the difference in odds of receiving therapy between children from one neighborhood category to those from the preceding less disadvantaged one (e.g., disadvantaged versus moderate disadvantaged).
^C Reference refers to reference group.
