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 utilization of volcanic powders, specifically basalt powders (BPs), as filler materials in the synthesis of geopolymers has gained significant attention in recent years. This study aims to investigate the potential application of basalt powders (BPs) in the synthesis process of geopolymers to develop more environmentally friendly structural materials. A comparative analysis was conducted, beginning with reference samples-geopolymers formulated exclusively from metakaolin and alkali-activated materials incorporating various types of BPs supplemented with differing amounts of metakaolin. The synthesis process was characterized by evaluating parameters such as volume density, compressive strength, and flexural strength. The most advantageous results, in addition to those achieved with metakaolin (MK), were observed for samples with a material ratio of 1:2:10 (NaOH: Na₂SiO₃:BP + MK) and a curing temperature of 20 °C, irrespective of the type of BP and the quantity of MK included. Furthermore, the inclusion of basalt resulted in a significant cost reduction of up to 80%, enhancing competitiveness against traditional Portland cement.
