ICED OUT: integrated cold-chain eliminating disease outreach. Piloting a motorcycle-enabled laboratory transport system combatting visceral leishmaniasis in rural Kenya.
Article in Frontiers in public health, 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
The fight against neglected tropical diseases (NTDs) in sub-Saharan Africa, particularly visceral leishmaniasis (VL) among Kenya's Pokot tribe, exemplifies the need for improved last-mile healthcare delivery systems. The Pokot face high disease burdens due to their pastoral lifestyle, socioeconomic hardship, and comorbidities such as malnutrition and high exposure to communicable diseases. Despite the availability of VL diagnostics and treatments, limited healthcare access in remote Baringo County exacerbates the disease's endemicity. This study describes a motorcycle-based cold chain transport model for VL diagnostics and vaccine transport in East Pokot, Kenya, utilizing phase-change material (PCM)-cooled transport backpacks. A Likert survey of ten key informants from six healthcare facilities identified critical challenges, including laboratory transport costs, interfacility distance, and lack of cold chain services. Three routes connecting these six facilities to more advanced healthcare facilities were established based on identified gaps. Transport schedules were synchronized with village market days to reduce costs and increase accessibility and frequency. Sample collection was further integrated into World Vision and Kenya Red Cross outreach campaigns. Diagnostic care was thereby extended to over 99 Pokot villages during the pilot period. Implementation revealed key insights into barriers to Pokot health-seeking behaviors, including cultural inhibitors and tribal conflict-related challenges. This model demonstrates potential through its linkage of isolated healthcare facilities, creating greater value efficiency and lower barriers for integration into existing community healthcare frameworks. Lessons learned during the pilot phase can guide implementation of similar community-enabled cold chain transport systems in global regions with healthcare fragility.
