Free Triiodothyronine as a Biomarker for Ventricular Arrhythmia Following Myocardial Infarction: A Multicenter Prospective Cohort Study.
Article in Clinical interventions in aging, 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
Background: The relationship between plasma free triiodothyronine (FT3) levels and the risk of ventricular arrhythmias (VA) in patients with acute myocardial infarction (AMI) remains unclear. Objective: This study aimed to investigate whether the level of FT3 influences VA in patients with AMI. Methods: A multicenter prospective study was conducted to collect patients diagnosed with AMI from three centers between January 2018 and December 2021. Patients were categorized into VA and Non-VA groups. FT3 levels were compared between groups, and multivariate logistic regression analyses were performed to evaluate the relationship. Results: A total of 3277 consecutive patients (mean age: 64.6 years) were included, with 123 (3.9%) developing VA during hospitalization. The VA group had significantly lower FT3 levels compared to the Non-VA group ([3.74 ± 0.77 pmol/L] vs [4.13 ± 0.81 pmol/L], Conclusion: This study confirmed a significant association between plasma FT3 levels and the risk of ventricular arrhythmias during hospitalization in patients with myocardial infarction. Low FT3 levels are associated with an increased risk of VA in patients with AMI.
