Optical coherence tomography-defined radial artery calcification: frequency, phenotypes, and correlates in a retrospective transradial PCI cohort.

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
Background and aims: The frequency, distribution, and optical coherence tomography (OCT) features of radial artery calcification (RAC) remain poorly defined. We assessed OCT-defined RAC and factors associated with patient-level RAC. Methods: This single-center retrospective observational study included 461 patients with analyzable radial artery OCT (RA-OCT) between January 2021 and August 2025. RAC was assessed at the patient, segment, and lesion levels. Clinical characteristics, radial artery plaque features, coronary OCT findings, and factors associated with patient-level RAC were evaluated. Results: Among 461 patients in the final analytic cohort, OCT-defined RAC was identified in 61 (13.2%). RAC involved the proximal, middle, and distal segments in 17/461 (3.7%), 25/461 (5.4%), and 52/461 (11.3%) patients, respectively. Among 214 calcified lesions, spotty calcification was the most common morphology (151/214, 70.6%). In exploratory patient-level analyses, all five radial artery plaque features were associated with RAC after multivariable adjustment, and all associations remained significant after Benjamini-Hochberg false discovery rate correction. In multivariable analysis, older age, diabetes mellitus, and coronary calcific nodule remained associated with RAC, whereas coronary calcium score was not statistically associated with RAC after adjustment. Conclusions: In this cohort, OCT-defined RAC was identified in 13.2% of patients, was more frequent in the distal segment, and showed heterogeneous lesion-level phenotypes. Older age, diabetes mellitus, and coronary calcific nodule were associated with RAC. Exploratory analyses also showed associations between RAC and multiple noncalcified radial artery plaque features.
