1 · What the graph read from it

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.

2 · The registry

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

objectivesSurgical decisions for ulcerative colitis are complex and preference-sensitive. This study aimed to assess patient preferences for surgical treatments, quantify preference heterogeneity, and examine individual-specific preferences to inform decision making.

methodsPatient preferences were elicited using a discrete choice experiment. A rigorous selection process involving focus groups and interviews with clinicians and patients resulted in 7 key attributes. Each task included 2 unlabeled surgical alternatives and a medication opt-out. A D-efficient fractional factorial design was generated. The survey was pilot tested using "think-aloud" interviews. Data were analyzed using multinomial and mixed logit models, with conditional mean coefficients used to estimate individual-specific choice probabilities.

resultsThree hundred and fifty patients completed the survey. Results showed significant preference heterogeneity for most attributes. The preference for the medication opt-out revealed a multimodal conditional distribution, clustering patients who strongly preferred, were indifferent to, or disliked medication. The interaction term "planning to have children" fully explained the preference heterogeneity in the fertility attribute. A gender interaction term showed that male patients had a stronger negative preference for a stoma. Choice probabilities showed individual differences; some patients had a 97.98% probability of preferring medication, whereas others had only a 0.09% probability, instead showing a high preference for surgical options.

conclusionsThis study demonstrates the value of using conditional distributions to examine preference heterogeneity. Simpler models failed to reveal the wide range of preferences present in the data. Conditional choice probabilities can be used to better understand how different patients make treatment decisions.
