a
Adjusted for age, birth year, gender, race/ethnicity, type of caregiver, caregiver education level, primary language, birth weight, BSID test version, region of country, site size, and rural/urban site classification, all at the levels shown in Table 1.
b
From F test in multiple regression model, adjusting for all of the above covariates; for maternal viral load, from trend test of decreasing scores with increasing viral load.
