Peer-learning and support among health policy and systems research actors in West Africa: a social network analysis.
Article in Health research policy and systems, 2025. 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
backgroundHealth policy and systems research (HPSR) is vital for strengthening health systems, yet its development in West Africa remains constrained by limited capacity. To strengthen capacity, the West African Network of Emerging Leaders in Health Policy and Systems (WANEL) was created to foster peer learning and cross-country collaboration among early- and mid-career HPSR actors. This study used Social Network Analysis (SNA) to examine WANEL's structure and functioning, with the aim of understanding how well the network supports its capacity and HPSR field-building goals.
methodsA cross-sectional whole-network survey was conducted with all 103 WANEL members, supported by document reviews and qualitative interviews. Relationship types assessed included acquaintance, communication, advice, mentorship and research collaboration. Data were analysed using Gephi to visualize relational patterns and compute metrics such as density and centralization, while qualitative findings provided context for interpreting network dynamics.
resultsWhile WANEL has enhanced cross-country awareness and disciplinary diversity, the network exhibits low cohesion and high centralization. Key support relationships, particularly mentorship, advice and collaboration are sparse and unevenly distributed. A few actors dominate the flow of information and access to opportunities, while many, especially early-career and francophone actors, remain peripheral or isolated. Network interactions are driven by prior relationships and linguistic or professional affinity, limiting broader engagement.
conclusionFindings reveal structural barriers that constrain WANEL's potential to act as an inclusive platform for HPSR capacity-strengthening. To fulfil its vision, the network must address its current fragmentation by building stronger cross-cutting ties, broadening participation and decentralizing influence. This study contributes empirical insights into the design and governance of regional HPSR networks in low- and middle-income contexts and underscores the importance of relational infrastructure in advancing collective capacity.
