Navigator excursion accuracy during exercise session (n = 19)*
| Navigator | Laboratory | Difference | Absolute difference | |
|---|---|---|---|---|
| Baseline glucose (mg/dl) | 161 (118–220) | 172 (122–239) | −17 (−26 to +18) | 23 (17–36) |
| Drop in glucose (mg/dl) | 82 (35–101) | 91 (51–129) | −15 (−29 to −2) | 16 (8–29) |
| Time to nadir (min) | 100 (70–100) | 78 (55–106) | +13 (+8 to +21) | 13 (8–21) |
| Rate of change (mg · dl−1 · min−1)† | 0.8 (0.5–1.1) | 1.2 (0.7–1.8) | −0.3 (−0.4 to −0.1) | 0.3 (0.1–0.4) |
↵* 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.
