1 · What the graph read from it

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.

2 · The registry

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, the fracture response of ternary geopolymer concrete (GC) comprising fly ash, slag, and silica fume reinforced with jute and sisal fibers was systematically examined under modes I, III, and mixed-mode loading regimes. Fiber lengths of 20, 40, and 60 mm at 0.5% by volume were incorporated to evaluate their influence on the fracture behavior. Employing the edge-notched disc bend configuration, this study quantified the effects of fiber type on the stress intensity factors, fracture toughness, effective fracture parameters, and mode mixity. The primary objective of this study is to clarify the mechanisms by which natural fibers influence crack initiation, propagation, and mode interaction in geopolymer concrete, thereby addressing existing deficiencies in the understanding of out-of-plane shear fracture and mixed-mode fracture behavior. The results revealed that the natural fibers significantly enhanced the GC fracture resistance, with optimum performance at a fiber length of 40 mm. Sisal fibers increased the mode I fracture toughness from 0.86 to 1.07 MPa·m
