The effect of promotional health message framing on the perceived benefit of mammography: evidence from estimation of willingness to pay.
Trial report in Journal of health, population, and nutrition, 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
backgroundEvidence from behavioral economics has shown that framing health information can impact the demand for screening. We examined the effect of promotional message framing on mammography demand by estimating willingness to pay (WTP).
methodsThis experimental study was conducted in 2024 over a period of 3 months. The interesting outcome was a WTP for mammography. 354 women were randomly selected and randomly assigned between the two study arms. The intervention involved the presentation of health information in two frames of gain and loss. The mammography demand has been estimated using robust standard error Logistic regression. Demand rate of mammography has been compared between two types of information framing using the chi-square test. Finally, the monetary value of willingness to pay (WTP) for mammography was estimated using the methodology developed by López-Feldman. All analyses were done using STATA 17.
resultsThe price and income elasticity of mammography demand were estimated as - 0.19 and 0.24, respectively (P < 0.01). The higher demand rate in the loss frame compared to the gain frame (38.7% vs. 25.1%) was statistically significant, and its effect size was estimated to be 0.282 (p < 0.01). The value of WTP in the loss frame (10.68 US$) was estimated to be more significant than in the gain frame (4.74 US$) (p < 0.01).
conclusionThis study suggests that health educators consider the message's persuasiveness with the type of health action before designing health messages. Moreover, health practitioners should use health messages with a loss frame to increase the demand for screening services such as mammography.
