  • a Calculated by EPC authors unless otherwise noted that study investigators provided data. Prevalence values were not estimated or weighted to reflect sampling

  • b Predictive values may be questionable for studies in which prevalence exceeded 10%; the problem arises when investigators choose a random sample of children with negative screens to complete the reference measures.

  • c Study investigators provided data.

  • d Could not calculate because of lack of data in article.

  • e Calculated as infinity.
