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
In this study, high-density polyethylene (HDPE) composites reinforced with palm kernel shell (PKS) fillers with mixed particle sizes were prepared using melt-extrusion compounding. A 5-ton hydraulic hot-press machine was employed to fabricate samples for tensile testing, with a focus on understanding the influence of varying filler sizes on the mechanical properties of the HDPE/PKS composite. The 30 wt% PKS composites demonstrated an elastic modulus (E) of 1.08GPa, ultimate tensile strength (UTS) at 14.13MPa, yield strength at 8.6MPa, stress at failure 12.87MPa, and elongation at failure 5.16%. However, the incorporation of larger PKS particles (PKSL) had a detrimental effect on the tensile properties, with increasing PKSL content leading to significant reductions in tensile properties. For example, for 7.5 wt% PKSL, E decreased by approximately 18%, yield strength by 37%, UTS by 24%, stress at failure by 29%, and total elongation by 62%. Similar trends were observed for the composites containing 15 wt% and 22.5 wt% PKSL. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were employed to assess the melting temperature ranges and thermal stability of the composites, respectively. Scanning electron microscopy (SEM) provided insights into the failure mechanisms, revealing weak filler-matrix interfacial bonding with larger particles, resulting in debonding and ultimately compromising the tensile properties of the composite.
