  1. When n values in subgroups are lower than the total group, infants were unable to complete the examination due to fragility or were awake for the habituation section
  2. #Equal variance assumed according to Levine’s test for equality of variances
  3. @Equal variances not assumed according to Levine’s test for equality of variances
  4. *p value significant at the 95% confidence level
