Hidden Beats: Detection of Subclinical Atrial Fibrillation Using Questionnaires in Young Adults and Its Cardiovascular Risk Profile.

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
Objectives: The objectives were to identify subclinical AF in young individuals and to examine its association with cardiovascular risk profile and quality of life (QoL) in a young adult cohort. Design: A cross-sectional survey was conducted with 403 adults aged 18-40 years in public and private hospitals. Methods: The INTERHEART Modifiable Risk Score (IHMRS), Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire, and the Modified European Heart Rhythm Association (mEHRA) were used to collect data. The statistics were performed using descriptive statistics, Spearman's correlation, the Mann-Whitney U test, the Kruskal-Wallis test, and multiple linear regression in IBM SPSS 26. Results: Of the 403 respondents, the majority were male (85%) and aged 36-40 (30%). A stronger negative correlation with QoL (0.42, p < 0.001) and a weaker positive correlation with cardiovascular risk (0.13, p = 0.009) were observed between higher EHRA symptom severity and cardiovascular risk. There was also a negative correlation between QoL and IHMRS (r = -0.29, p = < 0.001). Women presented with greater symptoms and low QoL (p < 0.001). The regression analysis showed that predictors of better IHMRS were age, male gender, higher EHRA scores, physical inactivity, and a family history of CVD. In contrast, better QoL was a protective factor (p < 0.01). Conclusions: Subclinical AF symptoms were highly correlated with increased cardiovascular risks and decreased QoL in young adults. Early detection of high-risk individuals, especially in settings with limited resources, could be achieved through simple questionnaire-based screening.
