Radiation Dose Estimation and Lifetime Attributable Risk of Radiation-Induced Cancer from Chest CT in COVID-19 Patients.
Article in Irish journal of medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundComputerized tomography (CT) scans for COVID-19 diagnosis have increased throughout the pandemic. This growth has raised concerns about the potential radiation-induced cancer risk. This study aimed to estimate the effective dose (ED) and lifetime attributable risk (LAR) of cancer incidence and mortality associated with a single non-contrast chest CT scan for COVID-19 pneumonia diagnosis.
methodsA retrospective analysis included 522 consecutive COVID-19 patients who underwent a single non-contrast chest CT at Gaza Strip hospitals (September 1, 2020-September 30, 2022). The ImPACT CT Dosimetry spreadsheet (Version 1.0.4) was used to estimate organ and effective doses. The XrayRisk.com calculator was used for calculating the LAR of cancer incidence from a single chest CT.
resultsThe study analyzed non-contrast chest CT scans of 522 patients, with a mean age of 50.9 ± 15.8 years, and 239 males. The mean ED was 3.6 mSv, with the highest organ doses in the lungs and breast. Female patients were at a higher risk of cancer, with a higher risk in younger age groups. The mean LAR of lung cancer incidence was 5.8 per 100,000 males, while breast cancer incidence was 6.6 per 100,000 females. The whole-body ED of a single non-contrast chest CT is equivalent to 12 chest radiography series and three mammography screenings, or approximately four months of natural background radiation.
conclusionChest CT scans for COVID-19 patients carry a low but measurable cancer risk, particularly for younger and female patients. The long-term health impacts of such exposure should be closely monitored.
