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 an innovative approach to improving the fracture toughness and sustainability of hybrid epoxy composites by synergistically reinforcing Gossypium (cotton) and E-glass fibers with silicon carbide (SiC) microfillers (20-50 μm, 0-15 wt%). Unlike conventional natural fiber composites limited by poor interfacial bonding, this work optimizes the hybrid laminate architecture and filler dispersion to achieve enhanced crack resistance. Composite laminates were fabricated via a controlled hand lay-up and compression molding process, followed by Mode I fracture toughness (GIC) and compact fracture toughness (KIC) testing per ASTM D5528 and D5045 standards using a 30 kN Instron 3365 frame. Results demonstrated that 15 wt% SiC composites attained the highest GIC = 0.82 kJ/m², while 10 wt% SiC achieved the maximum KIC = 1.52 MPa√m, confirming optimal energy dissipation through crack deflection, bridging, and fiber pull-out suppression. SEM fractography revealed uniform filler dispersion and strong interfacial adhesion with minimal voids, validating the improved load transfer and reduced delamination. Compared to unfilled controls, SiC-filled hybrids exhibited a 47% increase in GIC and 38% improvement in KIC, aligning with literature benchmarks for automotive-grade composites. The innovative combination of renewable cotton fibers with high-strength glass and ceramic fillers offers a sustainable, high-toughness material suitable for automotive body panels, undertrays, and interior structures where lightweight and damage tolerance are essential.
