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
Introduction Cardiomyopathies (CMs), as well as primary electrical disorders, i.e., inherited arrhythmia syndromes (IAS), including long-QT syndrome, catecholaminergic polymorphic ventricular tachycardia, and Brugada syndrome, predispose children to malignant ventricular arrhythmias and out-of-hospital cardiac arrest; survival depends on rapid Basic Life Support (BLS) and early automated external defibrillator (AED) use. We evaluated whether a brief, caregiver-focused, arrhythmia-tailored BLS workshop improves knowledge and affects short-term state anxiety. Materials and methods The study included 12 caregivers of children with cardiac conditions who participated in BLS training. The study was conducted in three stages: a pre-test (entry survey), intervention (lecture and practical training), and post-test (exit survey). Knowledge was assessed using custom questions based on the ERC 2025 guidelines, and anxiety levels were measured with the State-Trait Anxiety Inventory (STAI). Statistical analysis was performed using Wilcoxon, Mann-Whitney U, and Kruskal-Wallis tests. Results The mean knowledge score increased from 5.3 ± 1.0 before training to 7.8 ± 1.0 after training (T = 0.0; p = 0.002). The most significant improvement was observed in practical aspects of resuscitation, such as the compression-to-breath ratio during pediatric CPR. Anxiety levels, measured using STAI-X1, decreased after the training, and the difference was statistically significant (T = 5.5; p = 0.009). Conclusions BLS training effectively improves the knowledge of caregivers of children with IAS, which may enhance their competence in emergency situations involving sudden cardiac arrest (SCA). Further research in a larger group is needed to determine the impact of regular and repeated BLS training on long-term knowledge retention, as well as on anxiety levels and quality of life among families of children with CM or IAS.
