Other study design characteristics (method of data collection, who enrolled the participants, and incentives) and patient characteristics (cancer type, patient or parent age, and sex) did not affect participation in either paediatric or adult studies.
Data abstracted included: stillbirth/perinatal mortality rate, number of stillbirths, and statistical significance; study variables including country, study population characteristics, date of data collection, and study design; and dependent variables.
Data were extracted on the key study characteristics, design, methods of data collection, participant characteristics, results and conclusions drawn by authors.
Details of patients characteristics and methods of data collection appear in the sources cited.
We extracted the following background information: country, location, urban/rural, year of the publication and data collection, setting characteristics, and method of data collection and calculation of costs and income loss.
2. What are the features of post discharge surveillance systems used in the UK in terms of coverage; source of denominator data; diagnostic characteristics; other data collected; methods of data collection?
Of the 22 documents, 15 had specific recommendations on the characteristics of the methods of data collection that are most relevant for CBR (see Table 3).
In spite of attrition, the cohort's demographic characteristics, at two points of data collection remained comparable.
Time-invariant characteristics were measured during the earliest waves of data collection, and time-varying characteristics relevant to early development were measured repeatedly.
Means ± standard deviations were calculated for physiological and biomechanical characteristics using the last minute of data collection for each speed and BWS.
