Distribution of selected characteristics by mt204 allele in participants stratified by race.

*The strata labeled “All” includes pilot participants who were not called in array genotyping but were called by the secondary mt204 assay and excludes participants with inconsistent calls across assays.
†t-test with unequal variance for comparison of continuous characteristics, Fisher's exact χ2 for categorical comparisons.
‡Missing BMI for some participants: white, all nT = 3613, nC = 87; white, non-pilot nT = 3319, nC = 81; black nT = 538, nC = 30.
§Missing diabetes mellitus status for some participants: white, all nT = 3608, nC = 87; white, pilot nT = 283, nC = 7; white, non-pilot nT = 3316, nC = 81; black nT = 525, nC = 28.
