Relationship between size-specific dose estimates and image quality in coronary computed tomography angiography depending on tube voltage and scan field of view.

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: Advances in computed tomography (CT) technology have driven rapid development in cardiac applications, and achieving a balance between image quality and radiation dose has become a current research focus. This study aimed to quantitatively evaluate the effects of tube voltage and scan field of view (SFOV) selection on image quality and radiation dose in coronary CT angiography (CCTA), and analyze gender differences, thereby facilitating the development of personalized scanning protocols for patients. Methods: A total of 120 patients who underwent CCTA examinations on a 256-row CT scanner were retrospectively included and divided into eight subgroups based on tube voltage, SFOV, and gender. Patients' axial images were collected, with volume CT dose index (CTDI Results: Under different tube voltage and SFOV settings, both CTDI Conclusions: Due to differences in tissue structure, female patients receive a higher radiation dose during CCTA. The CTDI
