Relative Contribution of High-Dose Outliers to Cumulative Occupational Radiation Dose in the Catheterization Laboratory.

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: The contribution of high radiation dose outliers to cumulative occupational radiation dose is understudied. Methods: Physician radiation data were collected during consecutive coronary cases, and per case doses were ranked by magnitude. The relationship between the per case rank and relative contribution to cumulative dose was summed for cases ≤50th percentile and for cases >90th percentile. A similar methodology was applied for radiation doses among structural interventionalists, interventional echocardiographers, scrub technologists, and nurse circulators. Multivariable logistic regression was fit to identify independent predictors of physician radiation dose >90th percentile during coronary cases. Results: Across 363 coronary cases, the median physician radiation dose per case was 10.2 (3.2, 35.5) μSv, and the cumulative radiation dose was 13,230 μSv. Coronary cases ≤50th percentile accounted for only 5.0% of the cumulative radiation dose. Cases >90th percentile accounted for 60.3% of the cumulative dose. Cases >90th percentile accounted for 51.3%, 39.9%, 45.8%, and 64.8% of the cumulative dose among structural interventionalists, interventional echocardiographers, scrub technologists, and nurse circulators, respectively. ST-segment elevation myocardial infarction (OR, 6.2; 95% CI, 1.5-26.3; Conclusions: Physician radiation dose outliers contribute disproportionately to the cumulative radiation dose, with cases above the 90th percentile accounting for 60% of the cumulative dose. High radiation dose outliers are an important target for future radiation mitigation efforts.
