  • In the standard group (ST), hyperglycemia prompted insulin therapy; in the ultrasound group (US), it prompted an AC>p75. All P values for panel B and C >0.05.

  • *

    * Three women with AC>p75 who were not treated with insulin because of low glucose values were included;

  • one woman with AC>p75 who was not treated with insulin because of AC misclassification was included.
