Event-Based surveillance (EBS) implementation in unstable and conflict settings: lessons learned from Sudan.
Article in Conflict and 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
backgroundEvent-Based Surveillance (EBS) collects signal information from communities and other sources to improve the early detection and response to outbreaks or other public health threats. With the ongoing conflict in Sudan, a major disruption has posed to the health services including Indicator-Based Surveillance (IBS), and EBS has become particularly imperative during this challenging time. This article documents the experience of EBS implementation in Sudan, highlights the practical measures to keep EBS functioning in responding to the evolving war, and shares the lessons learned.
methodsA descriptive qualitative synthesis and desk review of the EBS project aggregated reports, tools, and documents were carried out. Data were organized into themes and analyzed manually using a thematic analysis, paying particular attention to the best practices in the development of EBS, innovations, challenges, and lessons learned.
resultsEBS in Sudan has successfully established and sustained a network of community volunteers nationwide. The EBS unit collaborated with partners and implemented many innovative ideas to train and communicate with the EBS focal persons at the state level and community volunteers during the conflict. Data and information generated by the system were integrated with the IBS data and used for decision-making at the Emergency Operating Centre (EOC). The drivers for success include careful selection of volunteers, addressing their needs, and maintaining communication with them.
conclusionsDespite the limited resources and the current war, the system kept functioning, and its core activities were maintained. The commitment of both partners and the Government of Sudan is an asset that should be strategically leveraged to expand this surveillance to areas that can benefit from EBS the most.
