Structural analysis and causal loop modelling: an integrated systems approach to analysing perinatal service delivery in carceral settings in Ontario, Canada.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn Ontario, Canada, incarcerated individuals and their newborns have adverse health outcomes. Perinatal care delivery in these settings is complex and fragmented across health, social service and carceral systems. This study aimed to apply and demonstrate an integrated systems-based analytical approach to examine dynamic interactions within carceral perinatal care and to identify influential variables and leverage points for policy and service improvement.
methodsUsing qualitative interview data from individuals who experienced incarceration while pregnant and from healthcare and social service providers, we applied an integrated methodological framework combining structural analysis (MICMAC) and causal loop diagramming. This stepwise approach was used to identify system variables, map causal pathways and feedback loops, and assess influence-dependence relationships within Ontario's carceral perinatal care system.
resultsOur analysis identified two key variables as central drivers of system behaviour through reinforcing and balancing loops, respectively: carceral staff autonomy and availability of providers. High levels of carceral staff autonomy reinforce power imbalances by decreasing providers' autonomy, which in turn constrains perinatal care delivery. Availability of providers operates within a balancing loop, whereby increased availability strengthens incarcerated clients' autonomy and increases their knowledge of human rights. Advocacy was identified as a key leverage point for navigating power dynamics within the system.
conclusionsThis study demonstrates the utility of integrating structural analysis with causal loop modelling to examine institutional dynamics, constraints and leverage points in complex health service systems. By identifying advocacy and comprehensive rights training as potentially essential interventions, alongside policy modifications, these findings highlight actionable pathways to reduce power imbalances and improve perinatal health outcomes among incarcerated individuals and their newborns. The approach provides a transferable framework for understanding complex and fragmented service delivery contexts and for informing evidence-based health policy and implementation strategies.
