Multivariable logistic regression models for the association between screening with the Infant Toddler Checklist (ITC) at 18 months and developmental diagnosis at 3–5 years (n=488)
| Developmental diagnosis | ||||
| Unadjusted analysis | Adjusted analysis* | |||
| Predictor† | OR (95% CI) | P value | OR (95% CI) | P value |
| Positive ITC screen‡ | 4.96 (2.02 to 12.16) | <0.001 | 4.48 (1.72 to 11.64) | 0.002 |
| Concern for speech delay | 6.00 (2.19 to 16.44) | <0.001 | 4.78 (1.65 to 13.81) | 0.004 |
| Concern for other communication delays | 5.48 (2.01 to 14.89) | <0.001 | 4.46 (1.71 to 11.64) | 0.002 |
Bold=statistically significant findings at p<0.05.
*Adjusted for child age at follow-up in months, child sex, birth weight, maternal ethnicity, family income. All covariates were measured at baseline except child age which was at follow-up.
†Each row shows results from three separate models.
‡An ITC screen is positive if there is concern for speech delay and/or other communication delays.
