Transradial versus transfemoral neuroangiography in a tertiary pediatric hospital-a propensity score matched study.
Article in European radiology, 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
objectiveTo evaluate the feasibility and safety of transradial access (TRA) in comparison to transfemoral access (TFA) in pediatric neurovascular procedures. MATERIALS AND
methodsIn this single-center retrospective cohort study, 729 pediatric neurovascular procedures performed between January 2020 and December 2024 were reviewed, including 175 TRAs and 540 TFAs. Primary outcomes included technical success and adverse events, while secondary outcomes assessed radiation dose, fluoroscopy time, and procedural duration. Propensity score matching (1:1) was applied to adjust for imbalance in baseline covariates. Statistical significance was defined at p < 0.05.
resultsOne hundred matched pairs of TRA and TFA were analyzed (TRA median age 13.9 [IQR 11.7-15.3] years, 52 females; TFA median age 14.5 [IQR 11.6-16.4] years, 51 females). Technical success rates were similar between TRA (98%) and TFA (99%, p > 0.99). TRA was associated with a higher rate of vasospasm (7% vs 1%, p = 0.03) but a lower rate of hematoma formation (2% vs 9%, p = 0.03). Despite the longer fluoroscopy time in the TRA group (19.4 min vs 8.8 min, p < 0.001), the radiation dose and procedural time were comparable between both groups. Asymptomatic radial artery occlusion (RAO) was detected in 5.1% (9/175) of radial accesses. A sheath-to-artery ratio ≥ 1 was independently associated with RAO (odds ratio, 6.13; 95% CI: 1.32, 28.4; p = 0.02).
conclusionTRA is technically feasible for pediatric neurovascular procedures in a selected population. Further prospective studies should be performed to evaluate the mid to long-term outcome of patients with asymptomatic RAO. KEY POINTS: Question Despite widespread adoption in adult neurointerventional practice, evidence of transradial access (TRA) in the pediatric population remains limited. Findings TRA has a comparable technical success rate to transfemoral access (TFA) in a large cohort of neurovascular procedures in a selected pediatric population. Clinical relevance TRA is a technically feasible alternative to TFA for pediatric neurovascular procedures in a selected group of patients. Preprocedural ultrasound assessment of the radial artery and optimization of the sheath-to-artery ratio are essential for minimizing radial artery occlusion.
