Footnotes per outcome:
1) a) We rated down the certainty of evidence due to very serious risk of bias; b) Number of studies included in the network: 27 RCTs; Number of studies directly comparing the intervention with usual care: 1 RCT(s) (N=14); Number of comparison(s) informing the indirect estimate: 0 comparison(s). The range of follow up was from 2 to 24 months for the studies included in the whole network. The range of follow-up was Carr-2008 months in the studies directly comparing the self-management intervention versus usual care.
2) a) We rated down the certainty of evidence due to very serious risk of bias, serious inconsistency, and very serious imprecision;b) Number of studies included in the network: 31 RCTs; Number of studies directly comparing the intervention with usual care: 2 RCT(s) (N=258); Number of comparison(s) informing the indirect estimate: 2 comparison(s). The range of follow up was from 1 to 24 months for the studies included in the whole network.
