Most glucose meters allow patients to manually label each measurement with a meal tag, but as this utility is not always used, a completion procedure is needed.
Data were collected using a Discourse Completion Test (DCT).
EFL refusal data were collected using a discourse completion test (DCT), which was designed and further developed based on observational field note data.
Participants were asked to provide data at three time points; four, eight, and 12 months post-randomisation, using a self completion questionnaire to eliminate any observer bias.
We note that using a genotyping completion rate of 95% or more allows some SNPs of poor genotyping quality to enter the analysis; the alternative is to use a more stringent completion rate, such as 99%, which has the advantage of removing low-quality SNPs at the cost of removing some high-quality SNPs.
Expressive grammar is evaluated using a sentence completion task and assesses the ability to produce a variety of specific grammatical morphemes: nominal, adjectival, and verbal inflexion, irregular plurals, prepositions, passive structure, and pronominal clitics.
Physical activity was measured at all three time points using a self completion seven day recall diary in which participants were asked to record 10 minute bouts of light, moderate, and vigorous physical activity in the week before the assessment.
The survey was conducted in September 2010 using a self-completion questionnaire administered over the internet following approval from the Brunel University Research Ethics Committee.
The study was a descriptive cross-sectional survey of practice nurses working in general practice within a large, urban Health Board, using a self-completion postal questionnaire.
Using a self-completion questionnaire for most of the data collection maximises the sample size for a given budget, whilst retaining the original sample design.
