Patient decision aid-supported shared decision making and short-term decision-making outcomes in type 2 diabetes: a prospective observational comparative study.
Observational study in BMC medical informatics and decision making, 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
backgroundOur study utilized patient decision aids (PDA) to explore the influence of shared decision making (SDM) on type 2 diabetes patients' intention to use subcutaneous antidiabetic agents.
methodsA prospective observational comparative study was conducted involving 249 patients with type 2 diabetes who were referred by physicians and subsequently interviewed by pharmacists across different clinics. Patients were classified into two parallel groups based on routine clinical practice. A patient decision aid (PDA) entitled "Type 2 Diabetes: Oral or Subcutaneous Antidiabetic Agents for My Diabetes Control" was developed for this study. Data collection focused on patients' intention to initiate subcutaneous antidiabetic agents, post-test knowledge scores, and satisfaction with clinical visits. These outcomes were compared between the SDM group, which received pharmacist-facilitated shared decision making using a PDA, and the PDA self-completion (control) group, which received usual care and completed the PDA by self-review.
resultsA total of 249 patients were included (SDM group n = 123; control group n = 126). The SDM group had higher baseline disease severity indicators. After adjustment, the SDM group demonstrated higher decision-making (adjusted mean difference 0.59, 95% CI 0.17-1.00), knowledge (0.84, 95% CI 0.59-1.09), and satisfaction (1.86, 95% CI 0.98-2.73) scores compared with controls.
conclusionsPDA-supported shared decision making was associated with higher short-term decision-making intentions, knowledge, and satisfaction among patients with type 2 diabetes. These findings suggest that PDAs may support patients in considering injectable treatment options, although conclusions regarding treatment initiation or clinical outcomes require further longitudinal evaluation.
