Usefulness of an Additional Shielding Sheet for Reducing Radiation Exposure to Patients and Medical Staff during Interventional Radiology.

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: Interventional radiology (IR) procedures often require prolonged fluoroscopic imaging, resulting in substantial radiation exposure to both patients and medical staff. Although conventional protective devices are widely used, the scattered radiation beneath the procedural table remains inadequately shielded. Materials and Methods: An additional shielding sheet, fabricated from a discarded 0.25 mmPb lead apron, was developed to block the open space between the interventional table and lead curtain. Phantom-based simulations of bronchial artery embolization (BAE) and transarterial chemoembolization (TACE) have been performed. Optically stimulated luminescence dosimeters were used to measure the radiation doses in the radiosensitive organs of the patient and operator phantoms, both with and without an additional shielding sheet. This study also evaluated dose reduction in the presence or absence of personal protective devices (PPD). Statistical significance was determined using the Wilcoxon signed-rank test ( Results: When an additional shielding sheet was used, the patient dose was significantly reduced by 20.5% and 20.6% during BAE and TACE, respectively (both Conclusions: Additional shielding sheets significantly decreased radiation exposure in both patients and operators during IR procedures. This simple and cost-effective device complements existing shielding tools and enhances radiation safety in clinical practice.
