1 · What the graph read from it

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.

2 · The registry

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

High atomic number (Z) fillers in polymer matrices provide lightweight alternatives to conventional radiation shielding. Previous studies have examined fillers such as CdO, [Formula: see text], and [Formula: see text]. However, no prior work has investigated tantalum disulfide ([Formula: see text]) in polymer composites for gamma-ray shielding, leaving a clear gap in the literature. Here, we report the photon attenuation performance of high-density polyethylene (HDPE) composites containing 10-50 wt% [Formula: see text] over 0.06-2.0 MeV, evaluated by Geant4 Monte Carlo simulations and validated with XCOM data. At 80 keV, where enhancement is most pronounced, the 50 wt% composite achieved a mass attenuation coefficient of 2.88 ± 0.04 [Formula: see text]/g, corresponding to a 15.9 ± 0.21 improvement over pure HDPE. Composites with 35, 20, and 10 wt% [Formula: see text] showed enhancements of 11.55 ± 0.05, 7.07 ± 0.03, and 4.04 ± 0.02 times, respectively. Benchmarking against micro-CdO-HDPE confirmed competitive or superior attenuation across the photon spectrum. These results establish TaS
