The data were analyzed using a Repeated Measures Analysis of Variance computed on the individual test items (n = 36). The behavioral sequelae of treating moderate hyperbilirubinemia with phototherapy were not severe, although at 2 weeks of age the comparison infants scored higher than the treated infants on items dealing with state control and orientation. Many of the observed differences involved “modal” rather than “best” scores. The findings address the need to describe treated infants' typical behavior, and possible avenues of future research are discussed.en-USJournal Article2013-09-16Nelson CA, & Horowitz FD10.1016/s0163-6383(82)80038-6
