SECONDARY outcome

Timeframe: One hour

Population: Precision Coefficient of Variation (CV)was analyzed using meter results from subject data that had numeric values for duplicate A1c self-tests. Subject data was not used in this outcome measure analysis when there had been a protocol deviation or when one (or both) A1c self-tests resulted in an error code.

The average Coefficient of Variation (CV) was computed by calculating the square of the CV for each pair of A1c self-test results, averaging this square value over the number of subjects included in the analysis, and then taking the square root.

SECONDARY outcome

Timeframe: One hour

For the comprehension analysis, subjects were divided into 2 groups. One group (n=56 subjects) was given both written (Quick Reference Guide) and DVD instruction material. The other group (n=54 subjects) was given only written instruction material. First time failure (FTF) was defined as: * The subject could not use the product without HCP assistance. * The subject could not complete the test. User error rendered one or more parts unusable. * The subject completed the test after one or more mistakes; the result was an error code instead of a numerical value.
