E XERCISE 5-4
Do you think the results in Table 5-1 provide sufficient validation for
the BG risk indices? Why or why not? Consider ways for performing
a more credible validation.
The two data sets used in Figure 5-10 and Table 5-1 only serve as
illustrations of the capabilities of the LBGI and HBGI; they do not provide
a sound validation of these measures. Because we considered only two
subjects, it is likely some (or all) of the observed phenomena are
caused by chance. A credible validation should include a large number
of T1DM and T2DM subjects to minimize the element of chance
because of unavoidable differences in the patients' BG control. We
present the results of these analyses next.
1. Group Comparisons
We use data collected over three months for 600 subjects (277 with
T1DM and 323 with T2DM), all of whom used insulin to manage their
diabetes. HbA 1c was tested twice during the course of the study, at 1.5
and 3 months. The participants collected three to five BG measurements
per day for the entire period.
The following variables were recorded for each participant:
HbA 1c at 1.5 months
HbA 1c at 3 months
Minimal BG value for the 3-month period
Maximal BG value for the 3-month period
