Methods and design of included studies

  • Systematic reviews draw together the findings of different studies using structured methods, and describe how studies were found.
  • Literature reviews draw on a range of different studies but don’t always use structured methods or describe the methods used in detail.
  • Randomised controlled trials allocate people to different groups at the start of the study and then follow them up at the same time to see if there is a difference between groups. Because people are randomly allocated to each group, if there is a difference between the groups this should be due to whatever is being tested.
  • Non randomised comparisons (quasi trials) compare two groups, but people are not randomly allocated to each group so it is less clear whether any difference between groups is a result of whatever is being tested or something else.
  • Before and after studies look at what happens to a group of people over time. A measure is taken at the start of the study (before the intervention) and again later (after the intervention).
  • Interviews ask people questions in person or by telephone. The questions and answers tend to be longer and more in depth than surveys.
  • Surveys ask people a series of questions online, on paper or by telephone. The questions tend to be short and structured.
  • Observational studies (assorted methods) include focus groups, observing people’s behaviour or a mix of interviews, surveys, document analysis or other methods.
  • Data analyses or document analyses involves drawing information from existing documents or databases or analysing datasets that have been collected for another purpose.
  • Case studies use various methods to look at one organisation or group in detail to outline a narrative of what can be learnt from the specific example.
  • Case control studies look back over time and compare one group (the cases or group that something happened to or who have a certain condition) to another group.
  • Cost analyses can include a variety of methods for analysing the costs and savings of an intervention.
