To describe the development and application of logic model templates for systematic reviews and health technology assessments (HTAs) of complex interventions.', 'This study demonstrates the development of a method to conceptualize complexity and make underlying assumptions transparent. Examples from systematic reviews with specific relevance to Sub-Saharan Africa (SSA) and other low- and middle-income countries (LMICs) illustrate its usefulness.', 'Two distinct templates are presented: the system-based logic model, describing the system in which the interaction between participants, intervention, and context takes place; and the process-orientated logic model, which displays the processes and causal pathways that lead from the intervention to multiple outcomes.
Do logic models help make sense of complexity in systematic reviews and health technology assessments?
