Occupational radiation exposure and crystalline lens density in perioperative nurses: a short communication.
Article in BMC nursing, 2026. 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
backgroundThe rising use of C-arm fluoroscopy in operating rooms raises occupational safety concerns for perioperative nurses. They may face scattered ionizing radiation despite not being classified as radiation workers. This study compared posterior Crystalline Lens Density a key indicator of radiation-induced cataract among perioperative nurses working with C-arm fluoroscopy, interventional radiology staff, and a non-exposed control group to determine whether intermittent occupational exposure is associated with measurable lens changes.
methodsIn this Cross-sectional comparative study, 150 participants (50 perioperative nurses with C-arm exposure, 50 non-exposed or staff, and 50 interventional radiology personnel) underwent standardized ophthalmic examination. Pentacam Nucleus Staging quantified posterior lens density; the worse eye was analyzed. Groups were compared using chi-square tests and ANCOVA with Bonferroni correction.
resultsInterventional radiology personnel exhibited significantly higher crystalline lens density (8.99 ± 1.50) compared with both perioperative nurses (8.40 ± 0.69; mean difference: 0.53, p = 0.001) and the control group (8.20 ± 0.27; mean difference: 0.70, p < 0.001). No significant difference was observed between perioperative nurses and controls (mean difference: 0.17, p = 0.539). The frequency of posterior subcapsular opacities (6.1% vs. 3.0% vs. 2.0%, p = 0.001), PNS grade ≥ 1 (17.1% vs. 8.0% vs. 3.9%, p = 0.002), and overall cataract prevalence (19.5% vs. 6.0% vs. 4.0%, p = 0.001) were all significantly higher in the interventional radiology group, with no significant differences between perioperative nurses and controls.
conclusionPerioperative nurses showed no significant difference compared with unexposed controls. These findings suggest that intermittent C-arm exposure under typical distancing conditions poses minimal measurable risk. Specifically, such exposure does not appear to increase radiation-related lens changes.
