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
backgroundDistal transradial access (dTRA) has gained attention for its lower risk of vascular complications compared to conventional transradial access (TRA). However, its feasibility and safety in patients with out-of-hospital cardiac arrest (OHCA) undergoing emergency percutaneous coronary intervention (PCI) remain uncertain.
aimTo evaluate the procedural success, safety, and clinical outcomes of dTRA in OHCA patients undergoing emergency PCI.
methodsThis retrospective single-center study included 48 OHCA patients who underwent emergency PCI for presumed coronary etiology between January 2022 and December 2025. dTRA was the default access strategy unless contraindicated. Among them, dTRA was attempted in 44 patients. Patients in whom dTRA was successfully achieved were included in the main analysis. Clinical, procedural, and outcome data were comprehensively reviewed, including access-site complications and neurological status.
resultsdTRA was successfully achieved in 43 of 44 attempted cases (97.7%). The median door-to-balloon time was 67 min. Mechanical circulatory support was used in 38 patients (extracorporeal membrane oxygenation: 17; intra-aortic balloon pumping: 29). Access-site complications included one case of limb ischemia requiring amputation and three minor hematomas (EASY classification grade 3-5) with no major bleeding (BARC 3-5). The 30-day mortality was 51.2% (22/43), and among the 21 survivors, 14 (66.7%) achieved a favorable neurological outcome (CPC 1-2).
conclusionsIn this OHCA cohort requiring emergency PCI, dTRA was feasible and safe in the majority of patients, including those receiving mechanical support. However, critical ischemic complications may still occur under unstable systemic conditions, warranting careful patient selection and vigilant post-procedural monitoring.
