  • Apgar values are expressed as median with 5 to 95 percentiles in parentheses.

    The rest of the values are expressed as mean ± standard deviation.

    Control indicates normal nonasphyxiated term newborn infants.

    Significance is expressed as follows:

  • * P < .5;

  • ** P < .01 versus control group;

  • # P < .05 versus RAR group.
