Comparative study of adverse drug reactions among direct-acting oral anticoagulants and vitamin K antagonists using the EudraVigilance database.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Our aim was to compare adverse drug reactions (ADRs) associated with direct-acting oral anticoagulants and vitamin K antagonists from the European EudraVigilance (EV) database. The EV database is the system for the analysis of information on suspected ADRs that are authorised, or being evaluated in clinical trials, in the European Economic Area. Registered ADRs (from the groups "Gastrointestinal disorders", "General disorders and administration site conditions", "Injury, poisoning and procedural complications", "Nervous system (NS) disorders" and "Vascular disorders") for apixaban, rivaroxaban, dabigatran and vitamin K antagonists (VKA) were collected by age group (< 65 years; 65-85 years and > 85 years) and by sex. The proportional reporting ratio (PRR) was used to compare ADRs in relation to the anticoagulants tested. A total of 274,693 ADRs were analysed. For gastrointestinal ADRs, patients treated with rivaroxaban and dabigatran (PRR 2.17 and 2.51, respectively) were at significantly higher risks than those treated with apixaban and VKA (PRR 1.27 and 1.47, respectively), while risks for vascular disorders were increased by all anticoagulants that were tested. Lastly, none of the anticoagulants significantly increased the risk of ADRs within the NS group. Rivaroxaban and dabigatran were associated with a significantly higher risk of gastrointestinal ADR than apixaban or VKA. All anticoagulants increased the risk of vascular pathology while none of them demonstrated significant increased risk of ADR to NS.
