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 increasing risk of fire hazards and the environmental burden of construction and demolition (C&D) waste necessitate sustainable, fire-resistant building materials. This study investigates the potential of recycled aggregate concrete (RAC) reinforced with fibers to enhance high-temperature performance while promoting waste utilization. In the first phase, concrete mixtures with 0%, 25%, and 50% recycled aggregate (labeled RAC00, RAC25, and RAC50) were evaluated at 23 °C, 300 °C, and 600 °C. RAC00 exhibited a 16% reduction in compressive strength at 300 °C and over 50% at 600 °C. While RAC25 initially showed a 10-30% decrease compared to conventional concrete at room temperature, it exhibited only a 1% strength decline at 300 °C and a 28% reduction at 600 °C, making it the most effective composition for further study. In the second phase, steel fibers (SF) and polypropylene fibers (PPF) were incorporated into RAC25, yielding substantial tensile strength improvements: RAC25-SF increased by 5.6% at 23 °C, 24.8% at 300 °C, and 28.3% at 600 °C. RAC25-PPF showed a 12.5% increase at 23 °C but declined at higher temperatures, with a 9.9% decrease at 300 °C and 32.9% at 600 °C. SF enhanced strength across all temperatures, while PPF reduced performance above 200 °C. Fiber additions improved ductility, toughness, and moisture retention, mitigating crack propagation under heat. Statistical modeling using ANOVA and response surface methodology (RSM) confirmed high model validity (R
