Public preferences for robotic surgery across two cancer scenarios: a latent class discrete choice study.
Article in Journal of robotic surgery, 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
Public preferences for robotic surgery may reflect different responses to the technology, physician recommendation, cost, and clinical context. This study characterized latent preference profiles across colorectal and thyroid cancer scenarios using a joint model with shared class membership and scenario-specific utilities. A discrete choice experiment was conducted among 1,012 Korean adults. Colorectal cancer choices compared robotic and laparoscopic surgery, whereas thyroid cancer choices included robotic, endoscopic, and open surgery. Attributes included out-of-pocket cost, physician recommendation, and family or acquaintance influence; the thyroid scenario incorporated a scar-sparing profile. A joint latent class logit model shared class membership across scenarios while allowing scenario-specific utilities. Two- to four-class models were evaluated using multistart estimation, and a one-step model examined characteristics associated with class membership. The three-class model characterized context-sensitive (60.6%), technology-positive (29.1%), and conventional-surgery-oriented (10.3%) profiles (mean maximum posterior probability, 0.948). The technology-positive class favored robotic surgery in both scenarios but also responded to physician recommendation. The context-sensitive class had positive utility for the thyroid scar-sparing profile but negative incremental utility for robotic over endoscopic surgery. Higher technology acceptance (OR, 3.17; 95% CI, 2.49-4.03) and previous cancer experience (OR, 2.31; 95% CI, 1.20-4.45) were associated with technology-positive membership. Stated preferences among general adults for robotic surgery reflected distinct valuation profiles rather than a single pattern of acceptance. Apparent demand for robotic surgery may arise through different combinations of technology preference, physician recommendation, cost, and scenario-specific considerations. These demand-side preference patterns provide testable hypotheses about how public preferences may interact with provider adoption in the diffusion of high-cost surgical technologies.
