Evaluation of genetic-molecular causes of out-of-hospital cardiac arrest - from patients to families: the GenetiCA study.
Article in Resuscitation plus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06844851 (Evaluation of Genetic-molecular Causes of Out-of-Hospital Cardiac Arrest), which is not on this 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.

Abstract
Background: Out-of-hospital cardiac arrest (OHCA) is a public health priority. In patients aged ≤50 years, inherited arrhythmogenic and structural heart diseases represent a leading etiology, yet existing evidence is largely derived from small, selected cohorts, and population-based estimates of genetic contribution to OHCA in young are still lacking. Methods: A multicenter, prospective observational study enrolling all patients aged ≤50 years who experience a medically-caused OHCA in Lombardy Region (Italy). (ClinicalTrials.gov NCT06844851). Blood samples will be collected in the pre-hospital by Emergency Medical System during Advanced Life Support. Genetic analysis will be performed using Next-Generation Sequencing with a comprehensive multigene panel targeting inherited arrhythmogenic syndromes and cardiomyopathies. Pre-hospital clinical data, environmental air pollution data and clinical outcomes will be collected. Family members of probands carrying pathogenic (P), likely-pathogenic (LP), or uncertain variants will be offered genetic counseling and clinical evaluation. The primary outcome will be to determine the prevalence of inherited arrhythmogenic and structural cardiomyopathies among young OHCA cases in this geographic area. Secondary outcomes will assess regional variability, associations with initial rhythm, sex, environmental pollution, and survival according to genetic findings. Expected results: Based on the regional OHCA registry (LombardiaCaRe), approximately 575 resuscitated young OHCA cases are expected annually. P/LP variants are anticipated in 15-25% of cases, corresponding to 86-144 individuals/year. Discussion: GenetiCA study will provide the first population-based assessment of inherited cardiac diseases among young OHCA patients within an entire geographic region. It aims to clarify the genetic burden of OHCA, support targeted family screening with potential implications for public health policies.
