Distal radial artery access in the anatomical snuffbox for coronary angiography and intervention: A single center experience.
Observational study in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 2 of them syntheses that pooled it.
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
backgroundTo explore the feasibility and safety of coronary angiography (CAG) and percutaneous coronary intervention (PCI) via the distal radial artery in the anatomical snuffbox.
methodsNinety two patients who underwent CAG or PCI through distal radial artery access at The Second Affiliated Hospital of Zhejiang Chinese Medical University from September 2017 to March 2018 were included in our study. We collected baseline characteristics, number, and duration of arterial punctures, procedural success rate, postoperative compression time, the numerical rating scale (NRS) scores at 3 hours after procedure, complications, hospitalization duration.
resultsThe mean age was 69 ± 11years (44-92 years), and there were 57 males (62.0%). The diameter of the right distal radial artery and the more proximal right radial artery were 0.171 ± 0.05 cm, 0.213 ± 0.06 cm, respectively. On average, the number of puncture attempts was 1.52 ± 0.81, access time was 2.3 ± 1.78 minutes (0.33 - 8.72 minutes), access success was 95.7%, the postoperative compression time was 3.41 ± 0.76 hours (2-6 hours), the NRS scores at 3 hours was 1.53 ± 0.72 (1-4), and the mean hospitalization duration was 7.13 ± 4.02 days. Four patients underwent left distal radial artery access and 88 patients underwent right distal radial artery access. There were 3 local hematomas after procedure and 2 patients had vasospasm. There were no cases of major bleeding, arteriovenous fistula, radial artery occlusion, or hand numbness.
conclusionCardiac catheterization through the distal radial artery in the snuffbox is safe and feasible. The right distal radial artery access can be routinely carried out.
