Vonoprazan vs Proton Pump Inhibitors for Gastroprotection in Anticoagulated Patients: A Real-World Cohort Study.

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
Introduction Oral anticoagulation is associated with an increased risk of GI bleeding. Proton pump inhibitors (PPIs) are commonly used for gastroprotection but have pharmacologic limitations. This study examined whether vonoprazan is associated with different one-year bleeding and clinical outcomes compared with PPIs among anticoagulated adults. Methods We conducted a retrospective cohort study using the TriNetX database to identify adults receiving oral anticoagulants who initiated vonoprazan or a PPI between 2015 and 2025. Propensity score matching (1:1) was performed to balance demographics, comorbidities, procedures, concomitant medications, and baseline laboratory values. Outcomes were assessed one year after treatment initiation. The primary outcome was GI bleeding; secondary outcomes included all-cause mortality, blood transfusion, and hemoglobin level. Results After matching, 3,107 patients were included in each group. GI bleeding was lower with vonoprazan than with PPIs (55 (1.96%) vs 88 (3.18%); OR 0.61; 95% CI 0.43-0.86). All-cause mortality (177 (5.70%) vs 290 (9.38%); OR 0.58; 95% CI 0.48-0.71) and blood transfusion (≤10 (0.33%) vs 27 (0.88%); OR 0.37; 95% CI 0.18-0.76) were also lower with vonoprazan. Mean hemoglobin at one year was modestly higher with vonoprazan (11.76 ± 2.13 vs 11.54 ± 2.34 g/dL). Conclusions In a propensity-matched real-world anticoagulated cohort, vonoprazan use was associated with lower one-year GI bleeding and transfusion rates, with modestly higher hemoglobin levels, compared with PPIs. These findings are hypothesis-generating and warrant confirmation in prospective studies.
