Exacerbation of Intracranial and Gastrointestinal Bleeding in Patients Above 50 Years of Age Co-treated With Antidepressants and Anticoagulants/Platelet Inhibitors at a Lebanese University Hospital.
Article in Cureus, 2025. 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
BACKGROUND AND
objectiveDepression is prevalent in the elderly, to whom the administration of anticoagulants (AC) and antiplatelets (antiaggregants (AG)) is frequent. Antidepressants (AD) work on increasing serotonin levels in the central nervous system (CNS) and are thought to decrease serotonin levels in platelets, an important factor in homeostasis. The effect of the co-administration of AD and AC/AG on increased bleeding risk is controversial; hence, our objective is to determine the effect of AD and AC/AG co-administration on the exacerbation and severity of bleeding in the elderly. SUBJECTS AND
methodsA monocentric retrospective study was conducted at the Lebanese Hospital Geitaoui by reviewing charts of 135 patients with gastrointestinal bleeding (GIB) and intracranial bleeding (ICB) hospitalized between 2015 and 2020. Proportions of patients treated with AD and AG, AD and AC, AD alone, or untreated with AD were determined. The studied parameters were demographic variants, medical and surgical histories, medication profiles, hemostasis tests, computed tomography (CT) scans, magnetic resonance imaging (MRI), endoscopies, and characteristics of the bleeding classified according to the Bleeding Severity Measurement Score (BSMS).
resultsNo positive correlation was found between AD and AC/AG co-administration and bleeding. Factors such as gender, age, body mass index (BMI), alcoholism, smoking, hypertension, diabetes, history of malignancy, dyslipidemia, chronic kidney disease (CKD), and coronary artery disease (CAD) were not statistically associated with intracranial hemorrhage (ICH) or GIB. Prothrombin time (PT) and international normalized ratio (INR) were significantly (p < 0.05) associated with bleeding severity. Multivariate analysis showed that bleeding severity increases with the clinical diagnosis (p < 0.001) and in patients with heart failure (p = 0.023).
conclusionOur study could not prove the potential drug-drug interaction (DDI) between AC/AG and AD. With the increased prevalence of mental disorders and prescribed antidepressants, proving the potential drug-drug interaction is of major importance. More research with diverse approaches on a larger scale is required in this regard.
