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
Background: The accumulation of polyethylene terephthalate (PET) plastic waste poses environmental and sustainability challenges due to its non-biodegradable nature and limited disposal options. Repurposing PET as aggregates in structural lightweight concrete (SLWC) offers a dual benefit of waste valorisation and conservation of natural resources, while supporting circular economy objectives. Methods: Eight experimental mix proportions of SLWC were developed using a factorial design approach, with water-to-cement ratios ranging from 0.40 to 0.45. PET aggregates were produced via thermal-mechanical processing and subjected to calcium hypochlorite treatment to improve surface bonding with cement paste. Standard tests were conducted to determine workability (Vebe time), fresh and dry densities, compressive strength, splitting tensile strength, and water absorption. Structural efficiency was also computed as a strength-to-weight performance indicator. Results: The fresh and dry densities of the PET-based SLWC ranged from 1455-1515 kg/m Conclusions: This study confirms that PET aggregates can be successfully utilised to produce structurally viable and durable lightweight concrete. Although workability is reduced, the compressive strength, tensile strength, density, and durability criteria align with international standards. These results demonstrate a sustainable strategy for PET waste valorisation in construction, contributing to resource conservation, reduced environmental burden, and advancement of circular economy goals.
