When comparing these two groups, their 4YR IQ difference was highly significant (C/R, p = 1.379 × 10 –4 ; Figure 1a , middle panel).
When comparing these two groups, their 4YR IQ difference was highly significant (C/R, p = 1.379 × 10 –4 ; Figure 1a , middle panel).
When compared between females/males, singleton/twin birth, full‐term/preterm, and with/without maternal disorders, significant differences were observed between term–preterm (P/F, p = .039) and singleton–twin birth (T/S, p = .018), while marginally significant differences were observed between children with and without maternal disorder diagnosis (D/nD, p = .103, Figure 1a , middle panel), suggesting that twin status, preterm birth, and maternal disorder diagnosis can be viewed as potential risk factors for lower IQ.
