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: Treatment burden (TBN) refers to the impact of patients' healthcare-related workload on their functioning and well-being. A high TBN has been associated with lower adherence to treatment and increased risk of major adverse events, and patients considered a TBN score of ≥59 points as unacceptably high. In the present analysis, we explored differences in TBN, the prevalence of unacceptably high TBN score and discern the contributory factors associated with TBN among patients receiving vitamin K oral anticoagulants (VKA) or non-vitamin K oral anticoagulants (NOAC). Methods: In a single-centre cross-sectional study from April to June 2019, consecutive patients receiving medical care at the Cardiology Clinic of University hospital were invited to fulfil the TBN Questionnaire encompassing 17 questions assessing TBN. Results: Of 514 study patients, 320 (62.3 %) were taking oral anticoagulant therapy (OAC) and were included in the present analysis. Of those, 206 patients (64.4 %) were prescribed a VKA. The mean TBN score was significantly higher in VKA versus NOAC patients (48.8 ± 26.5 vs. 41.8 ± 19.7, Conclusion: In the present study, VKA patients reported significantly higher TBN and more frequently unacceptably high TBN compared to NOAC, primarily due to numerous VKA-food interactions and the need for regular INR monitoring. Our findings suggest that the prescription of NOAC could reduce the TBN, which could translate to improved patient outcomes.
