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

Strain-diluted dissipation has emerged as a promising technique to modulate the quality (Q) factor of resonant nanoelectromechanical systems (NEMS). However, comprehensive understanding and precise control of this effect under varying temperatures have remained elusive. Here we investigate the temperature-modulated dissipation dilution mechanisms in two-dimensional (2D) NEMS resonators. We develop an explicit temperature-dependent dissipation dilution model highlighting the roles of thermally-induced strain and temperature fluctuations during vibration, which well captures experimental observations: with temperature increasing from 77 K to 355 K, Q factor in graphene resonators first decreases and then increases, while that in molybdenum disulfide (MoS
