Footnotes per outcome:
1) a) We rated down the certainty of evidence due to serious risk of bias, serious imprecision; b) Number of studies included in the network: 178 RCTs; Number of studies directly comparing the intervention with usual care: 0 RCT(s) (N=0); Number of comparison(s) informing the indirect estimate: 1 comparison(s). 2) 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: 0 RCT(s) (N=0); Number of comparison(s) informing the indirect estimate: 1 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 months in the studies directly comparing the self-management intervention versus usual care. 3) a)We rated down the certainty of evidence due to, serious imprecision;b)Number of studies included in the network: 8 RCTs; Number of studies directly comparing the intervention with usual care: 0 RCT(s) (N=0); Number of comparison(s) informing the indirect estimate: 1 comparison(s). The range of follow up was from 1 to 24 months for the studies included in the whole network. 4) a) We rated down the certainty of evidence due to very serious of risk of bias; b) Number of studies included in the network: 329 RCTs; Number of studies directly comparing the intervention with usual care: 1 RCT(s) (N=71); 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. The range of follow-up was 6 months in the studies directly comparing the self-management intervention versus usual care.
