"Basically a PR exercise…": a qualitative study of expert perspectives on 'performative versus evidence-informed' dengue vector control in the Asia-Pacific region.
Article in BMJ global 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
backgroundDengue cases are increasing despite continued efforts to control its vectors, with the Asia-Pacific region projected to bear a substantial proportion of the global burden. However, literature on dengue vector control methods and evidence use in national control programmes in the region is limited. We thus aimed to explore expert perspectives on current methods and how to improve dengue vector control programmes across the region.
methodsWe conducted remote semi-structured interviews with a purposive sample of 23 dengue vector control experts with experience in the Asia-Pacific region, analysing data using an abductive thematic approach.
findingsParticipants indicated that monitoring, evaluation and operational research related to dengue vector control methods was deprioritised in many countries across the region and that national vector control resources were often directed to relatively inefficient yet highly visible insecticide-based methods such as adulticide fogging. They suggested additional investment in other forms of vector control, including
conclusionsThe focus on visible and familiar methods evinces political concern for performative vector control. While understandable, refocusing national dengue vector control priorities on monitoring and evaluation/research evidence and mobilising communities can help Asia-Pacific countries improve
