Apgar scores in the case group with and without polycythemia at one-minute were 4.1\u00b11.8 and 6.6\u00b12.1, respectively and at 5 minutes were 6.9\u00b11.7 and 8.5\u00b11.4 respectively. Hematocrit correlated positively with Apgar scores (both at one and five minutes) in cases without polycythemia ( r\u200a=\u200a0.221, p\u200a=\u200a0.034 and r\u200a=\u200a0.255, p\u200a=\u200a0.014). Hematocrit of polycythemic newborns did not correlate with Apgar scores ( r\u200a=\u200a\u20130.287, p\u200a=\u200a0.491 and r\u200a=\u200a\u20130.436, p\u200a=\u200a0.281).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>The incidence of polycythemia is significantly higher in newborns of women with HDP and these polycythemic neonates had a significantly higher incidence of birth asphyxia.
