NA=not applicable.
*Selection=clear selection criteria; measurement times=adequate and clear time period between measurements; replication=sufficient detail to permit replication of test; blinding=blinding of those performing tests to previous monitoring results; reporting=reporting of uninterpretable test results; reference standard=same reference standard used across sample; attrition=information on attrition; checking=adequate checking of self monitoring readings; equipment validation=all measurement kit validated or not.
