| Model terms | β (SE) | χ2 | P-value | OR (95%CI) |
| Global: 4 to 6-year-old (n = 680) | ||||
| Best fit model: χ2 (d.f. 4) = 172.43, P < 0.001, AIC = 633.63, AUC = 0.795 | ||||
| Intercept | −2.26 (0.17) | 172.57 | < 0.001 | |
| 1. Are you concerned about the way your child talks? | 0.48 (0.25) | 3.66 | 0.056 | 1.61 (0.99, 2.62) |
| 2. Do other people have difficulty understanding your child? | 1.06 (0.25) | 18.16 | < 0.001 | 2.90 (1.78, 4.73) |
| 5. Has a family member/teacher commented that your child talks little or talks poorly? | 1.17 (0.23) | 25.63 | < 0.001 | 3.21 (2.04, 5.05) |
| 8. Compared to other children of the same age, does your child have difficulties understanding questions? | 0.64 (0.26) | 6.20 | 0.013 | 1.90 (1.15, 3.14) |
β (SE): regression coefficient (standard error). χ2, Wald’s χ2; OR (95% CI), odds ratio (95% confidence interval).
