Obstetric Life Support Education for Maternal Cardiac Arrest: A Randomized Clinical Trial.
Trial report in JAMA network open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05355519 (Advances in Patient Safety Through Simulation Research), which is not on this map. Cited by 7 papers.
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.

Abstract
Importance: Management of maternal cardiac arrest (MCA) requires understanding the unique physiology of pregnancy and modifications to life support. Health care professionals have historically demonstrated inadequate knowledge and skills necessary to treat MCA. Objective: To evaluate the effect of Obstetric Life Support (OBLS) education on health care professionals' cognitive performance, skills, and self-efficacy in managing MCA. Design, Setting, and Participants: In this single-masked randomized clinical trial, 46 health care professionals, including emergency medical service and hospital staff representing diverse specialties, were randomized to intervention or control groups at a single academic medical center in Farmington, Connecticut between May 1, 2022, and July 23, 2023. Intervention: The intervention group received OBLS education, which included a blended learning curriculum with simulation-based training on common maternal medical emergencies that lead to MCA. Participants were assessed for knowledge, confidence, and skills (eg, megacode scores as team leaders during MCA simulations). Intervention participants were compared with control group participants who received no OBLS education. Main Outcomes and Measures: The primary outcome was cognitive scores. Secondary outcomes included megacode scores rated by experienced OBLS instructors masked to assignment groups, combined assessment pass rates, and cognitive and confidence scores at baseline and 6 and 12 months after education. Data were analyzed from January 2024 to May 2024. Results: Forty-six participants (mean [SD] age, 41.1 [16.2] years; 24 [52%] women) were randomized. Despite most participants holding certification in basic and advanced cardiac life support, significant between-group differences were identified in knowledge, skills, and confidence. Mean (SD) cognitive scores were 79.5% (9.4%) in the intervention group vs 63.4% (12.3%) in the control group (P < .001). Mean (SD) megacode skills were higher in the intervention vs control group (91.0% [5.0%] vs 61.0% [12.0%], P < .001), as were confidence scores (72.7 [13.3] vs 56.2 [17.9] points, P = .002). Combined assessment pass rates were 90% in the intervention group compared with 10% in the control group (P < .001). Conclusions and Relevance: In this randomized clinical trial, OBLS education significantly improved health care professionals' knowledge, skills, and confidence in managing MCA. These findings underscore the urgent need for implementation of a standardized MCA curriculum nationwide, especially as the US continues to face unacceptably high maternal mortality rates.
