Figure 1

The comparisons of MDI score by different frequency of nighttime awakenings among infants (A) and toddlers (B). Error bars are standard error. Analysis of covariance (adjusted for recruited province, age and sex) and least significant difference post hoc analysis were conducted. Asterisks indicate statistical significance: * = P < .05, ** = P < .01. BSID = Bayley Scales of Infant Development, MDI = Mental Development Index, PDI = Psychomotor Development Index.
