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
Purpose: Due to the extensive use of radiation in various fields, such as food safety, sterilizing surgical materials, and medical diagnostics, it is essential to minimize radiation exposure for both patients and healthcare professionals, even at low doses. To meet this requirement, a composite film has been developed using polyvinyl alcohol (PVA) polymer and nitro blue tetrazolium (NBT) dye to measure low radiation doses effectively. Methods: Various concentrations of NBT dye (ranging from 0.75 to 15 g/L) were tested to determine the optimal concentration for maximum efficiency. The films were exposed to low doses of X-rays ranging from 20 to 100 mGy. Results: The PVA/NBT films exhibited good stability for 30 days after irradiation when stored in darkness. UV-visible absorption spectra showed a peak at 376 nm, shifting to 384 nm after exposure to X-rays. Furthermore, the response curve based on UV-Vis absorptions revealed a linear increase in absorbance with increased radiation doses up to 60 mGy (R = 0.99). XRD analysis indicated significant structural rearrangements in films with higher NBT concentrations and radiation doses. Specifically, X-ray irradiation caused two distinct peaks to shift from 2θ = 20.12° and 40.18° to 2θ = 19.66° and 41.24°. SEM analysis revealed that exposure to increased radiation doses resulted in significant morphological changes in PVA/NBT films, resembling torn tree trunks, especially with higher NBT concentrations. The preparation method was validated by XRF analysis, and the solubility of the NBT salt was excellent, with an R Conclusion: The PVA/NBT dosimeter containing 10 g/L of NBT shows promising potential as an effective alternative for the prompt and accurate detection of low X-ray doses in diagnostic radiology.
