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
Introduction: Although coronary angiography adjunctive technologies (AT) provide valuable insights into lesion severity and characteristics, their use increases radiation and contrast exposure. Aim: To assess the impact of AT on patients' radiation dose, irradiation and procedural times, and contrast usage. Material and methods: Dose-area product (DAP), patient effective dose, irradiation and procedural times, and contrast usage were compared between two groups, each comprising 258 patients who underwent coronary angiography with AT (AT group) or without (NoAT group). Multivariate analysis was performed on the whole patient group and the AT group to identify significant predictors of elevated DAP and contrast. Results: Compared to the NoAT group, DAP, patient effective dose, and contrast usage increased by 70-73%, while irradiation and procedural times were 120% and ~135% longer, respectively, in the AT group. Whole patient group analysis revealed that AT use was the strongest predictor of increased DAP and contrast usage (1.7; 95% CI: 1.6-1.8; Conclusions: In real-world clinical settings, the use of AT led to significant increases in patients' radiation dose, irradiation and procedural times, and contrast usage.
