AI-Enhanced Point-of-Care Diagnostics for Infectious Diseases in Resource-Limited Settings: A Scoping Review.
Article in Tropical medicine & international health : TM & IH, 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
objectivesTo systematically map the extent and nature of research on AI-enhanced point-of-care (POC) and rapid diagnostic technologies for infectious diseases in resource-limited settings, and to identify gaps in disease coverage, geographic representation and validation rigour.
methodsThis scoping review followed JBI methodology and PRISMA-ScR guidelines. The protocol was registered on OSF (https://doi.org/10.17605/OSF.IO/KV8MP). Five databases (PubMed, Embase, Scopus, Web of Science and IEEE Xplore) were searched for studies published from January 2015 to March 2026. Title/abstract and full-text screening used rule-based keyword screening with manual validation (Cohen's kappa = 0.856). Data were extracted using a 19-variable charting form and enriched with PubMed Central full texts.
resultsFrom 1072 records, 551 remained after deduplication and 237 studies were included. Publication volume grew exponentially, with 44% published in 2025-2026. COVID-19 (32%), malaria (27%) and tuberculosis (14%) dominated; neglected tropical diseases accounted for fewer than 8%. Microscopy (21%), molecular diagnostics (17%), biosensors (14%) and rapid diagnostic tests (14%) were the most common modalities. Convolutional neural networks predominated (26%), followed by random forests (10%) and support vector machines (8%). Only 7% of studies reported prospective field validation, while 62% did not report validation level. Geographic analysis revealed concentration in East Africa and South Asia, with underrepresentation of West Africa and Latin America.
conclusionsAI-enhanced POC diagnostics for infectious diseases in resource-limited settings is a rapidly growing field facing critical gaps in validation rigour, disease equity and geographic representation. Only 16 of 237 studies (6.8%) report prospective field validation. Future research should prioritise field validation, expand beyond the COVID-19/malaria/TB triad and involve end-user communities from the design stage.
