Fifty years of maternal mortality research in sub-Saharan Africa: a bibliometric analysis of trends, gaps, and opportunities for health equity.
Review in Frontiers in global women's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Sub-Saharan Africa (SSA) continues to bear a disproportionate share of the global burden of maternal mortality (MM), despite decades of advocacy, research, and investment. Methods: A bibliometric analysis investigated the evolution, volume, scope, and impact of maternal mortality research in SSA from 1975 to 2024, and presents a 50-year overview of peer-reviewed research on maternal mortality across SSA, identifying trends, prolific contributors, research gaps, and thematic shifts over the studied years. Moreover, using the Scopus database and VOSviewer, 1,985 publications were analyzed for authorship, institutional output, funding patterns, and coauthorship networks. Results: The results revealed substantially increased publication output over time, particularly from Nigeria, South Africa, and Ethiopia, though the regions remain dependent on external funding and underrepresented in global high-impact journals (≤2.6% of global MM research outputs). There were some critical disparities in authorship, language, and thematic areas, including the translation of research findings into policy and practice. The most cited studies were grounded in subnational and underserved populations in SSA. The highest MM rates were found in Chad, Nigeria, and South Sudan (>1,000 deaths/100,000 live births), yet Chad and South Sudan have been studied in the fewest publications. Persistent causes of maternal mortality such as postpartum hemorrhage, hypertension in pregnancy, unsafe abortion, and infection have remained unchanged for decades, while health system and sociocultural barriers, including geographic inaccessibility, conflict and internal displacement, continue to worsen clinical outcomes, undermining progress. Conclusion: This study underscores the broader systemic inequities in SSA that are reflected through progress in MM research and its outputs. Moreover, it calls for intersectional approaches in health, equity-driven, and transdisciplinary research and highlights the need for regional ownership, particularly in underrepresented areas. Capacity building and strengthening local research ecosystems through investments in research infrastructure and cross-sectoral partnerships to bridge research-policy gaps are recommended. Context-driven solutions are crucial to make tangible progress. Such solutions are aligned with the attainment of the Sustainable Development Goals and national health security plans.
