Summary of posterior distribution of FSIQ for each exposure profile cluster and the estimated difference in FSIQ compared to lowest exposure profile cluster at age 7-year resulting from the BPR (n = 255).
| Clusters | Adjusted Posterior Mean FSIQ a,b (95% Credible Intervals) | Mean FSIQ_c from FSIQ_CP3 a,c (95% Credible Intervals) | Probability FSIQ_c < FSIQ_CP3 d |

| CP1 | 95.5 (88.6, 102.0) | −6.9 (−11.7, −2.1) | 0.998 |
| CP2 | 100.1 (93.4, 106.3) | −2.4 (−7.2, 2.5) | 0.83 |

a Adjusted for child’s age at WISC assessment (mean centered), sex, language of assessment, maternal education, maternal intelligence (mean centered), maternal country of birth, maternal depression at 7-year visit, HOME score at 7-year visit (mean centered), household poverty level at 7-year visit, and prenatal urinary dialkyl phosphate (DAPs) metabolites (log10, mean centered); b The posterior distribution of the expected FSIQ scores for the cth cluster when holding fixed effect control variables at zero; c Difference between posterior distribution of expected FSIQ for the cth cluster compared to posterior distribution of expected FSIQ for cluster 3 (reference group) when holding control variables at zero; d Probability that the posterior distribution of expected FSIQ for the cth cluster is below the expected FSIQ for cluster 3 when holding control variables at zero.
