TL;DR: Systematic reviews of complex evidence cannot rely solely on protocol-driven search strategies, and primary sources must be identified by “snowballing” or by personal knowledge or personal contacts.

TL;DR: It is concluded that meta-narrative review adds value to the synthesis of heterogeneous bodies of literature, in which different groups of scientists have conceptualised and investigated the 'same' problem in different ways and produced seemingly contradictory findings.

TL;DR: This comprehensive review of reviews summarises current knowledge on the barriers and facilitators to implementation of diverse complex interventions in primary care and suggests that the “fit” between the intervention and the context is critical in determining the success of implementation.

TL;DR: Computer-based diabetes self-management interventions to manage type 2 diabetes appear to have a small beneficial effect on blood glucose control and the effect was larger in the mobile phone subgroup.

TL;DR: ICBI are effective tools for learning about sexual health, and they also show positive effects on self-efficacy, intention and sexual behaviour, and more research is needed to establish whether ICBI can impact on biological outcomes.
