Understanding delivery type as a mediator in the relationship between insurance type and permanent contraception fulfillment: a mixed-methods multi-site study.

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
introductionMany patients who desire postpartum permanent contraception cannot obtain it, with barriers linked to insurance type - particularly Medicaid's 30-day consent policy - and delivery type (cesarean vs. vaginal). This study uses a mixed-methods approach to examine whether delivery type mediates the relationship between insurance type and permanent contraception fulfillment.
methodsWe conducted a concurrent mixed-methods analysis of data collected from three US hospitals. We analyzed quantitative data from 2,794 patients (2018-2019) using mediation analysis to assess the indirect effect of insurance type on contraception fulfillment via delivery type. We also thematically analyzed qualitative data from semi-structured interviews with 67 patients and 54 obstetrician-gynecologists (2022-2023) to explore how delivery type influences contraceptive decision-making and service provision.
resultsMediation analysis showed a significant indirect effect of insurance type on contraception fulfillment through delivery type (average causal mediation effect: -0.06; 95% confidence interval [CI]: -0.10, -0.04). Medicaid patients had higher odds of delivering vaginally (odds ratio [OR]:1.78; 95% CI: 1.44, 2.21), and vaginal delivery was strongly associated with reduced fulfillment (OR: 0.05; 95% CI: 0.04, 0.07). Qualitative findings reinforced these results. Patients and providers described how Medicaid's consent policy delayed access, while cesarean delivery made permanent contraception easier. Providers more often discussed permanent contraception with patients already undergoing a cesarean delivery, and patients who delivered vaginally faced logistical challenges with follow-up care. DISCUSSION: Delivery type is an important mediator in the relationship between insurance type and postpartum permanent contraception fulfillment. Addressing policy restrictions, provider counseling disparities, and institutional constraints is critical to ensuring equitable contraceptive access.
