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
This study presents a sustainable method for recycling Ordinary Portland cement concrete (OPCC) using geopolymer technology, reducing the need for new cement and aggregates. By including geopolymerization, the process offers significant ecological and economic advantages over conventional methods. Crushed and pulverized waste concrete was used as recycled granulate (RA) and binder, using recycled clay brick powder (RBP) as an additive. Based on the results, the incorporation of RA into recycled geopolymer concrete (GRC) improved the compressive strength by 11.7%, with a maximum compressive strength of 44.3 MPa and a tensile strength of 4.77 MPa. Replacing recycled concrete powder (RCP) with 5% wt% resulted in a 21% reduction in compressive strength (35 MPa) and a 25.3% reduction in tensile strength (3.56 MPa). A further increase in the RBP content to 15 wt% reduced the compressive strength to 27.65 MPa (37.5% reduction). The RBP content directly effects on the flowability and improves the appearance of the GRC and reduces cracks. When comparing total eco-cost, GRC (128.9 €/m
