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
Epoxy resin filled with aluminum particles constitutes a polymer composite material commonly utilized in research and development departments to fabricate rapid tooling for prototyping new designs. This study developed aluminum-filled epoxy resin molds by incorporating surface-cooled cooling channels (SCCCs) to enhance cooling performance, validated through Moldex3D simulation and experimental analysis. The simulation revealed that a 1 mm mesh size was utilized to balance accuracy and efficiency, with simulations revealing the complete filling of the injection-molded product within 5 s. This study examines rapid tooling with surface-cooled cooling channels in low-density polyethylene injection molding. The reliable parameters include a melt temperature of 160 °C, a mold temperature of 30 °C, an injection pressure of 10 MPa, and a heat dissipation time of 20 s. These parameters effectively minimize the risk of mold cracking while ensuring efficient molding. The SCCC demonstrates superior cooling performance, enhancing cooling efficiency by 58.7% compared to the conventional conformal cooling channel. It reduces cooling time, enhances production capacity, and shortens delivery times. Additionally, it lowers energy consumption, carbon emissions, and the rate of product defects in large-scale manufacturing. A cooling mechanism of SCCC after LDPE injection molding was also proposed.
