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
rationaleThe migration of phthalate plasticizers from high-volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time-consuming solvent extraction and chromatographic methods that are often expensive and lack the throughput required for large-scale safety screening, this study intends to present a rapid screening method using direct analysis in real time coupled to high-resolution mass spectrometry (DART-HRMS) to monitor plasticizer migration in PVC films subjected to accelerated UV aging. Operational parameters, such as ionization gas temperature and grid voltage, were systematically optimized to balance desorption efficiency with molecular integrity.
methodsDART-HRMS analysis of three commercial PVC films subjected to accelerated UV aging (ASTM G154-23) was performed after optimization of the operational parameters: ionization gas temperature: 250 °C, 350 °C, and 500 °C and grid voltage: 50 and 350 V were systematically optimized to balance desorption efficiency with molecular integrity.
resultsAnalytical performance was strongly governed by source energy, with optimal conditions achieved at 350 °C and 50 V, yielding the highest signal stability and minimal in-source fragmentation. Elevated grid voltage (350 V) caused severe signal suppression and fragmentation, particularly for high-molecular-weight plasticizers such as DIDP and DINP. Application of the optimized method revealed formulation-dependent migration behavior during UV aging. Short-chain phthalates showed rapid and, in some cases, transient surface enrichment, whereas medium- and high-molecular-weight plasticizers exhibited delayed or limited migration, becoming detectable only after prolonged exposure.
conclusionsDART-HRMS provides a fast, robust, and solvent-free approach for screening plasticizer migration in PVC films. The optimized conditions enable sensitive detection while preserving molecular integrity, allowing differentiation of additive mobility as a function of molecular weight, formulation, and UV-induced degradation. This methodology offers a high-throughput alternative for assessing additive stability and potential release in consumer-grade PVC materials.
