Inclusion and exclusion criteria

Category	Included	Excluded
Population of interest	Crisis-affected populations receiving humanitarian assistance or aid in low-income or middle-income countries (as defined by World Bank, 2012): including refugees and internally displaced persons (see online supplementary appendix A for definitions of these terms)
Intervention	Any health-related intervention seeking to improve sexual and reproductive health (SRH) outcomes
Outcomes of interest	Primary quantitative research studies: indicators included self-reported use and/or confirmed use of the Minimum Initial Service Package (MISP) services (ie, use of emergency obstetric and newborn care services, use of condoms and/or contraceptives, use of HIV and sexually transmitted infection screening services, use of abortion services, use of adolescent health services and use of psychological support services by sexual violence survivors). Self-reported use is defined as when a beneficiary reports the use of a product or service without additional verification; this indicator is often biased. Confirmed use is defined as when the evaluation tests, observes or confirms a product or service was used in some way (e.g. via observation). Primary qualitative research studies: we included outcomes exploring the determinants of service utilisation of the MISP and its components.	Studies which do not evaluate utilisation of SRH interventions
Study types and design	Primary quantitative research studies: Study designs including randomised controlled trials, non-randomised controlled trials, controlled before-after studies, controlled interrupted time series studies, economic studies (cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis, economic modelling) of public health which the outcome is measured before and after the intervention or an intervention is studied against another intervention with baseline or control group. Primary qualitative research studies: Study designs including focus group discussions, in-depth interviews and structured observations, limiting studies to those with an observable contrast of time and/or a control group.	Studies on preparedness or resilience if not linked to an intervention evaluating the utilisation of SRH interventions Studies with no specific health intervention and no outcomes (ie, studies examining only health needs, prevalence, health risk-factors, co-ordination). Review papers; references listed in review papers were screened to find more primary data sources
Data type	Must include primary data	Includes only secondary data
Phase of humanitarian crises	Studies conducted during the acute, chronic and early recovery phases of a humanitarian crisis (defined in online supplementary appendix A).	Studies conducted after a humanitarian crisis has stabilised
