Assessment of Radiation Dose to Adult Patients Undergoing Cardiac CT.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study is designed to evaluate the radiation doses received by adult patients during cardiac computed tomography (CT) examinations. MATERIALS AND
methodsA retrospective study was conducted at a tertiary care hospital from May 2024 to August 2024. Patients aged over 20 years undergoing CT angiography on a GE Healthcare Revolution EVO CT scanner following the standard protocol were included. Dose length product (DLP) values were generated by the scanner software for each patient, and the effective dose (E) was subsequently computed. Linear regression analysis was used to assess the relationship between effective dose, body mass index (BMI), and injected contrast volume.
resultsThe mean value of effective dose was observed to be 13.55 mSv, with a minimum of value of 0.175 mSv and a maximum of 27.23 mSv. The median DLP was found to be 943.26 mGy.cm, with a minimum value of 12.47 mGy.cm. The linear regression analysis shows that there exists no dependence of effective dose on BMI and volume of the contrast injected.
conclusionThe effective dose mean was 13.55 mSv, with a DLP median of 943.26 mGy.cm. Our audit shows that the mean values of "E" surpass the United Kingdom National Diagnostic Reference Levels (NDRLs) for coronary CT angiography and coronary angiography, 4.3 mSv and 170 mGy.cm, respectively. These findings highlight the need for dose optimization in cardiac CT protocols.
