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

Ophiolitic suites derived from oceanic crust are rich in ferromagnesian and mafic minerals and exhibit relatively high densities, making them promising and economical materials for radiation shielding. This study evaluates ophiolitic rocks exposed along the Marsa Alam-Idfu road in the southern Eastern Desert of Egypt as natural radiation shielding materials, including mafic metavolcanics, mafic schist, serpentinite peridotites, and hornblende metagabbro-diorite. Comprehensive geochemical analyses were conducted using polarizing microscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FTIR) to constrain the mineralogical frameworks. Experimental γ-attenuation measurements were performed using a P-HPGe detector for Cs-137 (0.662 MeV) and Co-60 (1.173 and 1.332 MeV) sources. Monte Carlo simulations (MCNP-5) and EpiXs software were also employed to model photon interactions and validate the experimental results. The mineralogical assemblages of the investigated samples which predominantly composed of serpentine, chlorite, amphibole, plagioclase, talc, and carbonates, play a key role in controlling their radiation shielding properties. Geochemically, the rocks display a major oxide compositional range from ultramafic to mafic. Serpentinized peridotites, in particular, exhibit high MgO content and low silica, while mafic metavolcanics and schists are rich in Al
