Parental preferences for generic substitution policies for children in China: a discrete choice experiment.
Article in BMJ open, 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
objectivesTo investigate Chinese parents' preferences regarding generic drug substitution policies for children, to provide references for optimising these policies, enhancing parental acceptance rates of generic drug substitution for children, and improving paediatric medication accessibility.
methodsA discrete choice experiment was employed, and voluntary sampling was used to select parents with at least one child aged 0-12 years from three cities located in the eastern, central and western regions of China for a questionnaire survey. A mixed logit model was used to estimate preference coefficients for various policy attributes, the relative importance (RI) of these attributes and the acceptance rates of different policy scenarios.
resultsA total of 411 participants were included. Except for the generic registration standards, the differences in all other included attributes of the paediatric generic drug substitution policy were statistically significant (p<0.01). Generic consistency evaluation (GCE) (RI=41.30%) and medication control (RI=31.29%) were the most important attributes influencing participants' choice preferences. The acceptance rate of the current paediatric generic drug policy among Chinese parents was only 55.42%. However, if the policy scenario included differentiated registration standards, all generic drugs passing GCE, a 10% increase in reimbursement rate, autonomous choice of generic drugs and full postsubstitution management for all generic drugs, the acceptance rate could reach 83.31%.
conclusionsChinese parents show a stronger preference for GCE and medicine use control within paediatric generic drug substitution policies. To enhance policy acceptance rates, it is recommended to continue implementing GCE and to respect parents' autonomy in selecting medications for their children.
