Lessons for future outbreaks from successful contact tracing systems in Asia.
Review in The Lancet regional health. Western Pacific, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Countries around the world had utilized contact tracing to support public health responses to curb transmission during the COVID-19 pandemic. In particular, countries in East and Southeast Asia had been effective in their contact tracing responses. To understand their successes, the contact tracing systems of Japan, Thailand, Singapore and Vietnam were comparatively analyzed, including the technical aspects of contact tracing approaches, detection and response structures. Through the comparative analysis, we uncovered the key elements within these successful systems, namely speed, capture and accuracy, designed specific for the countries' settings. For the system to work efficiently, we found that maintaining the balance across speed, capture and accuracy while adapting to the disease epidemiology and environment was essential. Contact tracing will remain a vital strategy to control the next epidemic with a pandemic potential. The lessons learnt could provide guiding principles to help enhance contact tracing systems and prepare for future outbreaks.
