Key confounders

Minimum set of confounders that should be adjusted for (will vary per outcome)

  • Age
  • Severity of illness – may not be reported
The review strategy

Meta-analysis where appropriate will be conducted.

Studies in the following subgroup populations will be included:

  • Frail elderly
  • Case mix – Cardiovascular /Oncology patients etc.

In addition, if studies have pre-specified in their protocols that results for any of these subgroup populations will be analysed separately, then they will be included. The methodological quality of each study will be assessed using the Evibase checklist and GRADE.
