Comparative Safety Profiles and Usage Patterns of Iodinated Contrast Media in Medical Imaging.
Article in Diagnostics (Basel, Switzerland), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThis study aimed to analyze the usage patterns and hypersensitivity reaction (HSR) profiles of six nonionic iodinated contrast media (ICMs) used in computed tomography (CT) to enhance patient safety and inform evidence-based contrast agent selection.
methodsWe retrospectively reviewed 248,209 CT scans obtained between January 2020 and December 2022. Six ICMs (iomeprol, iohexol, ioversol, iopromide, iodixanol, and iobitridol) were compared on the basis of their usage rates, HSR incidence, and severity. This study also evaluated the impact of premedication protocol reinforcement and assessed the quarterly HSR rates.
resultsAmong the 248,209 CT scans, 1603 (0.65%) were associated with HSRs. Most HSRs were mild (86.2%), with moderate (10.9%) and severe (2.9%) reactions being less common. Four ICMs were used as first-line agents and two ICMs were used as second-line agents. The second-line agents, iobitridol and iodixanol, exhibited 7-8 times higher HSR rates compared to the first-line agents. A modified premedication protocol implemented in mid-2022 significantly reduced the incidence of moderate HSRs (
conclusionsThese findings highlight the importance of tailored premedication protocols and a 7-8 times higher rate of HSR with second-line agents in contrast-enhanced imaging. Future research should focus on elucidating the mechanisms underlying these variations to further refine contrast agent selection and management strategies.
