Table 11. Multivariate and univariate linear models, investigating whether delta-beta, delta-gamma, theta-beta or theta-gamma PAC at 4 months predicted either infant-led or parent-estimated language outcomes.

The table details the multivariate linear models followed by the univariate linear models describing whether PAC at 4 months predicted a) infant-led language measures or b) the parent-estimated language measures. Bonferroni correction for multiple comparisons in the univariate models led to modified significant alpha levels of, p = <0.01 for infant-led and p = <0.025 for parent-estimated (denoted by bold italic text). Modified alpha level for trends are p = <0.02 for infant-led and p = <0.05 for parent-estimated (denoted by bold text).
