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
The growing demand for sustainable solutions in civil construction has driven the use of industrial waste in the formulation of new materials. This study evaluated the alterability of artificial stone slabs produced with 87% ornamental stone waste (Dumont Quartzite and Preto São Gabriel Granite) and 13% epoxy matrix, using the vacuum vibro-thermo-compression technique. Alterability was tested against staining agents, chemical attack, wetting and drying cycles, UV radiation, salt crystallization, three-point flexural strength test after freeze-thaw cycles, and natural weathering. Quantitative results revealed high physical stability, with mass loss varying only between 0.11% and 0.23% in wetting and drying cycles. In salt crystallization, mass loss ranged from 0.38% to 0.47%, lower than the rates of 0.87% and 1.36% reported in the literature for similar materials. Regarding mechanical performance, freeze-thaw cycles caused reductions in flexural strength between 11.66% and 31.59%; however, the stones maintained final strength values above 20 MPa, classifying them as very high-strength materials. The results indicated good physical and chemical stability of the materials, with low mass loss and preservation of mechanical properties, except under UV radiation and natural weathering, which caused significant chromatic alterations. The data obtained demonstrate the viability of applying these stones in indoor environments, promoting the valorization of waste and contributing to the circular economy.
