Hi there, I’m Dr Trudi Deakin, chief executive of the charity X-PERT Health which develops, implements and evaluates structured education for the prevention and management of diabetes.

We strive to keep abreast of the latest research so that healthcare professionals and patients obtain the most up-to-date lifestyle management information. Literature reviews are undertaken on an annual basis and the research papers critically appraised to draw accurate and meaningful conclusions. The following hierarchical system for levels of evidence is used [1]:

Grading of evidence:

  • Ia: systematic review or meta-analysis of RCTs.
  • Ib: at least one RCT.
  • IIa: at least one well-designed controlled study without randomisation.
  • IIb: at least one well-designed quasi-experimental study, such as a cohort study.
  • III: well-designed non-experimental descriptive studies, such as comparative studies, correlation studies and case-control studies.
  • IV: expert committee reports, opinions and/or clinical experience of respected authorities.

Grading of recommendations:

  • A: based on hierarchy I evidence.
  • B: based on hierarchy II evidence.
  • C: based on hierarchy III evidence.
  • D: directly based on hierarchy IV evidence.
