Asian | 854 | 0.5% (4/854) | 0.0 (0.0–60.2)† | 99.5% (850/854) | 99.2 (98.3–99.7)† |
Black/African American | 314 | 45.9% (144/314) | 31.9 (20.2–57.8) | 54.1% (170/314) | 97.8 (80.0–100.0) |
White | 6118 | 2.0% (125/6118) | 16.7 (10.8–23.4) | 98.0% (5993/6118) | 98.8 (97.9–99.5) |
AF indicates atrial fibrillation.
There were no evaluable reference‐positive intervals within the Native Hawaiian/Pacific Islander or Other groups, so sensitivity could not be determined for these groups.
For the Asian group, some cluster bootstrapped estimates of CIs were incalculable or resulted in estimates of [0, 1] due to most events occurring in only a few subjects. The CIs reported above are estimated based on the exact binomial.
