Association between Dioxin-Like PCB concentration sum1 (dichotomized using a median split) and ASD and Non-TD
| ASD vs. TD | Non-TD vs. TD | ||||||
|---|---|---|---|---|---|---|---|
| Exposure | TD (n = 60) | ASD (n = 21) | Non-TD (n = 23) | OR (95% CI) | P-Value | OR (95% CI) | P-Value |
| Frequency (%) | |||||||
| Dioxin-Like PCB Lipid-Standardized Crude/Final Model2 | |||||||
| M1 (2.47 – 14.78 ng/g of lipid) | 29 (48) | 7 (33) | 16 (70) | Reference | Reference | ||
| M2 (14.83 – 46.18 ng/g of lipid) | 31 (52) | 14 (67) | 7 (30) | 1.87 (0.66 to 5.29) | 0.24 | 0.41 (0.15 to 1.14) | 0.09 |
PCB = Polychlorinated Biphenyl, TD = Typical Development, ASD = Autism Spectrum Disorder, Non-TD = Non-Typical Development, M1 = Lowest 50% PCB concentration, M2 = Highest 50% PCB concentration
