  • *

    * Does not include subjects who were too young for exercise test (n = 7), who had incomplete lab data during exercise (n = 1), whose Navigator was not functioning properly during exercise (n = 1), or whose glucose did not drop during exercise (n = 2).

  • Timed from baseline to the glucose nadir.
