Efficacy of tafamidis across age groups in ATTR-CM: insights from real-world data.
Article in Cardiology journal, 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
introductionElderly patients with transthyretin amyloid cardiomyopathy (ATTR-CM) remain underrepresented in clinical trials. This study aimed to evaluate the effectiveness of tafamidis 61 mg in patients with ATTR-CM across different age groups. MATERIAL AND
methodsPatients with ATTR-CM treated with tafamidis 61 mg were stratified into age groups: < 75, 75-85, > 85 years. Clinical and echocardiographic data were collected at baseline and follow-up. The primary outcome - cardiovascular-related hospitalization and cardiovascular death - was assessed using Kaplan-Meier analysis.
resultsA total of 89 patients with ATTR-CM were included: < 75 (n = 23), 75-85 (n = 40), and > 85 years (n = 26). Hereditary ATTR-CM was more prevalent in younger patients (p < 0.001). Older patients (≥ 75) were more often in NYHA class II/III (p = 0.009), required higher diuretic doses (p < 0.001), and had higher NT-proBNP (p = 0.002). At baseline, patients ≥ 75 years had greater maximal wall thickness (p < 0.001) and left ventricular mass (p = 0.034); global longitudinal strain was most impaired in those > 85 years (p = 0.039). Over a mean follow-up time of 27.4 ± 19.3 months, tafamidis treatment in patients > 85 years was associated with a greater reduction in NT-proBNP (p = 0.041) and in diuretic doses compared to those < 75 years (p = 0.044). No significant changes were observed in NYHA class, Kansas City Cardiomyopathy Questionnaire scores, or echocardiographic parameters. The composite outcome of cardiovascular-related hospitalization and cardiovascular death did not differ significantly among age groups (Log-Rank 5.71, p = 0.06).
conclusionsThis study underscores the benefits of tafamidis in elderly patients, including those aged > 85 years, and supports its use across all age groups to improve cardiovascular outcomes in ATTR-CM.
