Compliance and Contamination
"Of the 96 participants in the self-monitoring group, 63 carried out
more than 80% of the requested blood glucose monitoring (that is, four
fasting and four postprandial readings a week)."
Compliance is possibly a systematic problem in this study.
There is 65.6% compliance to the intervention, even with the laxity in
intervention compliance - "defined" as >80% of the monitoring expected.
Thus, with the compliance laxity, the worst case scenario gives 34.4%
contamination from self-monitoring to no monitoring.
