As a consequence, the present study used a quasi-experimental design that matched intervention health districts to control health districts.
In the few studies where classification and matched interventions have been used, meta-analysis showed a statistical difference in favour of the classification-based intervention for reductions in pain (both for short-term and long-term) and disability.
The commercial managed care plan had 6,371 of 7,101 (89.7%) matched interventions.
The program was organized as a multiple case intervention study, with matched comparison groups.
This is a prospective, non-randomised matched control before-and-after intervention study.
This matched controlled trial, the LEAP intervention study, was uniquely tailored to compare the intervention and control schools at baseline (March/April, 2010), post-testing (after 7-weeks; April-June, 2010) and at a follow-up (after 8-months; November, 2010).
In addition, the optimal design for an intervention study is to match the intervention subjects to control subjects and have all data collected and analyzed simultaneously.
The quasi-experimental design of this five-year intervention study allows us to match two communities in California's Central Valley with similar demographic characteristics.
The RESPECT study is a nationwide population-based prospective, controlled, mixed-methods intervention study looking at children aged 6-18 years newly diagnosed with cancer in eastern Denmark (n = 120) and a matched control group in western Denmark (n = 120).
2 For example, ICEMRs are employing an array of study designs including active, passive and reactive case detection, matched case control, longitudinal and control intervention studies, entomological surveys, spatial analyses, as well as laboratory studies employing a variety of molecular markers.
