Scores were calculated by taking the unweighted sum of standardised frequencies of intake for each food associated with the pattern, then dividing them into quartiles based on the distribution of the baseline cohort.
Although diet records with notebooks and scales can be more detailed and precise than standardised food frequency questionnaires, results from surveys of food intake have low reproducibility and, in particular, there are systematic errors in underreporting energy intake [ 22].
Key areas identified for further standardisation and/or investigation include (1) the treadmill acclimation protocol and markers of its efficiency, (2) the design and frequency of standardised exercise tests used, and (3) the interpretation of data for the development of effective and realistic conditioning programmes.
The most common summary measures of occurrence are frequency, incidence rates, standardised mortality ratio and relative risk (Beale et al. 2008).
In this case study, implementation of a standardised reporting form improved the frequency of inclusion of data in monthly reports.
The control condition consists of usual care including medication safety monitoring and ad hoc medication reviews on clinical indication that differs in quality and frequency, but no standardised 3MRs in the manner done in the intervention condition.
Frequency distribution of the standardised residuals of the GWR.
Further limitations were the use of a single item to measure sexual satisfaction, and non-standardised measures of changes to sexual frequency and sexual activities.
Participants also took part in audiometric screening with standardised headphones (THD 39) at the frequencies 250, 500, 1k, 2k, 3k, 4k and 6k.
The choropleth and classed symbol maps represented different types of summary measures: incidence rate (n = 27), relative risk (n = 10), frequency (n = 8), and standardised mortality ratios (n = 6).
