Escala Abreviada de Desarrollo, version 1a (EAD-1) percentilesb at 20 to 30 mo of age by domain and age at Zika symptom onset of children postnatally infected with ZIKVc and without adverse neurologic, eye, or hearing outcomes (N = 51d), Colombia, September-November 2017e. aThe EAD-1 is a standardised, validated developmental screening tool in Colombia. bEAD-1 scores from the sample were converted into percentiles based on the normed Colombian population. c Participants were laboratory-confirmed with ZIKV infection by serum rRT-PCR within one week of symptom onset at 1–12 mo of age. dFour children in the hearing-language domain and one child in the personal-social domain, whose respective domain scores could not be calculated due to incorrect EAD-1 application, were excluded. eThe four lowest percentiles in the personal-social domain are driving the correlation; if these four points were removed, the correlation is no longer statistically significant
