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

Quarry waste is a fine rock aggregate produced as a by-product of the rock-crushing process in quarries which is environmentally hazardous when poorly disposed. This paper presents the results of a study carried out to explore the feasibility of recycling basaltic quarry waste (BQW) with waste high-density polyethylene (HDPE) into sustainable construction materials. Recycled HDPE/BQW formulations were melt-mixed in a single-screw extruder and then transfer-moulded into experimental samples. No significant chemical transformations were detected by Fourier transform infrared spectroscopy. Thermogravimetric analyses showed an improvement in the thermal stability of HDPE with the addition of BQW. Scanning electron microscopy imaging revealed generally poor adhesion between the two phases. Both tensile and impact strength initially increased but decreased at higher filler loading. However, stiffness, compressive strength, compressive modulus, density, and hardness improved with filler content for all particle sizes. The increase in water absorption with increasing filler content was not significant. This study demonstrates that BQW is a suitable filler for HDPE and the resulting material may be used to make roofing tiles and paving blocks.
