Residents' preferences for inclusive commercial supplementary medical insurance: a discrete choice experiment.
Article in Health economics review, 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
backgroundIn China, inclusive commercial supplementary medical insurance (ICSMI) has developed rapidly, and the size of the insured population is critical for its long-term sustainability. To enhance the attractiveness of ICSMI and increase enrolment, it is necessary to improve scheme design based on residents’ choice preferences.
methodsA discrete choice experiment was conducted to elicit residents’ preferences for ICSMI. Seven attributes and their levels were identified through a literature review, analysis of policy clauses of existing ICSMI schemes, and face-to-face interviews. A D-efficient design was used to generate 20 choice sets. A mixed logit model was applied to estimate overall preferences for ICSMI, calculate willingness to pay for different attribute levels, rank the relative importance of attributes, perform heterogeneity analysis and scenario simulation analysis.
resultsAmong the 634 respondents, ICSMI schemes with lower premiums, government participation, broader coverage scope, lower deductibles, higher reimbursement ratios, reimbursement of pre-existing conditions, and one-stop settlement were preferred. Residents attached the greatest importance to the reimbursement ratio. The highest willingness to pay was observed for the coverage scope: respondents were willing to pay CNY 211.301 for the coverage scope from low scope to high scope. Subgroup and interaction analysis based on demographic characteristics showed heterogeneity in preferences for some attributes. Respondents with chronic diseases exhibited stronger preferences for a higher reimbursement ratio and one-stop settlement. When these two items are included in the product plan, their uptake rate will also increase significantly.
conclusionsResidents showed significant preferences for all attributes. This study provides preference evidence directly from the target insured population and offers a reference for optimising the design of ICSMI products.
