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

This study presents a molecular dynamics (MD) investigation of the sintering behavior and mechanical properties of cross-shaped silver (Ag) fivefold twinned nanowires (FTNWs). A model of two FTNWs arranged at 90° intersections was constructed and sintered at three temperatures (698, 898, 1098 K) with three heating rates (1.0, 0.1, 0.01 K/ps), followed by high-temperature relaxation and controlled cooling at 0.08 K/ps. After cooling, room-temperature relaxation was performed in the isothermal-isobaric ensemble using different time durations and reinitialized with different random seeds to ensure statistically independent velocity distributions and structural equilibration. Uniaxial tensile tests were then carried out at strain rates of 1.0 × 10 Supplementary Information: The online version contains supplementary material available at 10.1007/s00339-026-09778-7.
