    • * Patients without data (ie, not recorded as present, absent, or refused because the patient was not yet at an appropriate gestational age for the tests) for any test in groups 1 to 6 were excluded from the analysis of that particular group; therefore, n differs among each group.

    • † pre-EMR sample sizes in group 4 does not meet the minimum standard size of n = 30 for a normally distributed population.
