participants, interventions, comparisons and outcomes.
A data extraction template was generated and based on the study design, population, case definition, observation period, interventions, comparisons, and primary and secondary outcomes as well as the study quality.
There was significant clinical and methodological heterogeneity across studies in terms of the interventions, comparisons, and study designs.
Analysis of data collected will depend on its characteristics (participants, interventions, comparisons, and outcomes or methodology).
To reflect this, we first present a general PICO (participants, interventions, comparisons and outcomes) formulation, identifying the scope of the literature on self-management interventions we used.
7 Each question was rephrased according to the PICO (population, intervention, comparison, outcome) method with the population defined as adult RA, PsA or other rheumatic diseases, and specific interventions, comparisons and outcomes defined according to each question.
The relevant reviews identified were then analysed by categorising and comparing the populations, interventions, comparisons and outcomes that were reported for each review.
In order to identify SRs, one reviewer (CRB) extracted data regarding population, interventions, comparisons and outcomes (inclusion criteria) and evaluated the methodological quality of the included trials.
Inclusion and exclusion criteria for a review are the detailed listings of the types of population, interventions, comparisons and outcomes that a review will consider.
Data extraction Two reviewers independently assessed articles for inclusion, extracted data to assess risk of bias, trial methods, patients, interventions, comparisons, and outcome.
