Analysis of insecticide-treated bednet market dynamics between 2004-2021 and monetary value of additional bednet longevity.
Article in Cost effectiveness and resource allocation : C/E, 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
backgroundInsecticide-treated bednets (ITNs), a cornerstone of malaria prevention, are distributed via mass campaigns across Africa every three years, at huge cost to National Ministries of Health and development partners. While WHO sets global standards for ITNs as a public health commodity, they typically remain in use for less than the assumed three years, due to accumulation of damage, and retention times vary according to the product and use context. However, it is currently unclear whether ITN prices reflect their value in terms of physical durability.
methodsWe explored how various ITN product and market characteristics have influenced real ITN prices since 2004. We used ITN price and retention data across sub-Saharan Africa to calculate the country specific equivalent annual cost of ITNs and defined country-specific price thresholds that the market should be willing-to-pay to secure nets that would be retained and used for exactly three years or, separately for six months longer than current estimates suggest.
findingsThe ITN market has become less concentrated in the last two decades, but it remains dominated by a few large buyers and suppliers. ITN prices have decreased dramatically since 2010. Among individual sales, we found no evidence that increased durability is rewarded through higher price. The value for equivalent annual cost per person protected and the willingness-to-pay for a net that is retained for longer depends on baseline net price and is greater in countries with shorter existing ITN retention times.
interpretationSubstantial public health and efficiency gains could be realized if bednets were used for longer periods. However, achieving this requires changes in the market on both the supply and demand sides, including a shift towards value-based procurement. This approach would better incentivize manufacturers to innovate and invest in producing more durable nets by linking pricing to their long-term effectiveness. An explicit price threshold, along with improved information on net durability across different contexts, could help foster innovation and direct investment where it is most needed.
