Further comparisons among CME groups were undertaken with stratification by enrollment phase (i.e. whether or not practices were in the targeted enrolment group) and type of specialty (pediatric or family physician).
For each of the three groups, it represents a proportion of 20% or more of the total corresponding enrolment group at FMBS: 22% for students, 21% for the residents and 20% for the lecturers.
Another approach to avoid adverse selection is group enrolment, whereby groups such as co-operative members, or employers, or schools enrol together.
After enrolment, both groups were analyzed with a computerized test battery for Speech Perception Tests in silence and in noise background to assess speech perception disabilities.
Second, except for lipid-lowering therapies (i.e., statin and fish-oil therapies), at enrolment, treatment groups were well matched for other known clinical characteristics.
Despite high levels of enrolment, particular groups of children are marginalised in terms of access to quality education.
The experimental group was divided into two subgroups, depending on the study enrolment order: group A (n = 23) and group B (n = 25).
Additional children born into study compounds after 6 months: We will enrol children born into study compounds who are too young to meet our enrolment criteria (group 1, above), deliver interventions to them according to randomised assignment and measure anthropometry and diarrhoea at follow-up surveys.

A critical review of trials specifically addressing brain metastases shows key issues that could prevent acceptance of results by regulatory agencies, including enrolment of heterogeneous groups of patients and varying definitions of clinical endpoints.
