CI: confidence interval.

^a$\mathrm{Consistency}(\%)=\frac{\mathrm{Number\; of\; diabetes\; diagnosis\; in\; both\; test\; and\; retest\; study}}{\mathrm{Number\; of\; diabetes\; diagnosis\; in\; test\; study}}\times 100$.

^bThe numbers do not add up to 148 due to missing values on physical activity level.

^cThe numbers do not add up to 151 due to missing values on physical activity level.

^dThe numbers do not add up to 130 due to missing values on physical activity level.

^eThe numbers do not add up to 315 due to missing values on physical activity level.

^fThe numbers do not add up to 282 due to missing values on physical activity level.
