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
Passenger car waste tires (PCWTs) are difficult to recycle as asphalt modifiers due to their high styrene-butadiene rubber (SBR) content and poor compatibility with asphalt. This study investigates whether hexadecylamine (HDA)-assisted thermo-mechanical devulcanization can transform PCWT rubber into an effective modifier for styrene-butadiene-styrene (SBS)-composite-modified asphalt, and how rubber dosage influences the performance balance. PCWT rubber was devulcanized using HDA-assisted twin-screw extrusion and incorporated into 90# asphalt with 3 wt% SBS at 20 wt% and 30 wt% dosages, alongside non-devulcanized PCWT and truck tire rubber for comparison. Comprehensive characterization, including sol fraction, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS), dynamic shear rheometer (DSR), multiple stress creep recovery (MSCR), and bending beam rheometer (BBR), was conducted. The results demonstrate that HDA-assisted devulcanization effectively breaks sulfur crosslinks while preserving the rubber backbone, significantly improving compatibility and low-temperature performance. Increasing the devulcanized rubber dosage from 20 wt% to 30 wt% compensates for the reduced high-temperature stiffness, achieving a balanced performance profile comparable to truck tire rubber. The novelty of this work lies in establishing HDA-assisted thermo-mechanical devulcanization as a viable pathway for converting otherwise underutilized PCWT rubber into a high-performance asphalt modifier, thereby expanding the feedstock options for crumb rubber-modified asphalt.
