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
Achieving fracture toughness and sustainability in concrete remains a major challenge in modern construction. This study explores the synergistic effects of graphene nano-platelets (GNPs) and date palm fiber (DPF) on the mechanical and eco-efficiency performance of concrete. Eleven mix proportions with varying GNP (0-0.2%) and DPF (0-2.5%) contents were tested. Response surface methodology was employed to model five key properties-compressive strength, flexural strength, modulus of elasticity, split tensile strength, and ultrasonic pulse velocity. Pearson and canonical correlation analyses were used to examine property interrelations. Multi-objective optimization indicated that incorporating 0.199% GNPs and 0.99% DPF achieved optimal performance, enhancing compressive strength by 44%. The developed models exhibited high accuracy (R² > 0.96, desirability = 0.971). While GNPs increased embodied carbon, the overall approach balances performance, modeling precision, and sustainability, offering valuable insights for next-generation green infrastructure materials.
