From conversation to completion: identifying conversation elements to support effective shared decision-making for lung cancer screening in rural primary care.
Article in BMC primary care, 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
introductionShared decision-making (SDM) is required for lung cancer screening (LCS) and is intended to support informed, patient-centered decisions. However, SDM implementation in primary care remains inconsistent, particularly in rural settings where LCS uptake is low. This study examined which conversation elements within clinical interactions are associated with LCS completion and may support SDM discussions.
methodsWe conducted a cross-sectional survey with screening-eligible adults residing in rural Appalachian communities. Survey items were adapted from the DECISIONS instrument to assess conversation elements within LCS-related clinical interactions, information sources, content discussed, decision attributes, and post-conversation perceptions. Associations between conversation elements and LCS completion were examined using chi-square tests, t-tests, and multivariable logistic regression. Socioeconomic factors were explored to contextualize findings in a rural population with documented health disparities.
resultsProvider initiation of the LCS conversation and provision of educational materials were the two conversation elements independently associated with screening completion. Additional conversation elements, including elicitation of patient preferences and clear provider recommendations, were associated with screening completion in bivariate analyses. Use of educational materials and decision support aids was strongly associated with patients' perceptions of being informed and confident, which were in turn associated with LCS decisions. Socioeconomic indicators were associated with variation in several conversation elements relevant to SDM.
conclusionFindings highlight that discrete conversation elements that reflect SDM interactions are differentially associated with behavioral and perceptual outcomes, with provider initiation and educational materials linked to screening completion and decision support and clear recommendations linked to feeling informed and confident. Identifying and prioritizing a small set of key conversation elements that support SDM interactions may inform LCS delivery in rural primary care.
