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

γ-Irradiation significantly alters the mechanical properties and functions of poly(vinylidene fluoride) (PVDF), yet the molecular mechanism underlying its property evolution at high irradiation dose remains unclear. Because the single-chain inherent elasticity of a polymer directly reflects its backbone structure, single-molecule force spectroscopy (SMFS) was employed to examine PVDF under different γ-irradiation doses. The results show a progressive increase in chain flexibility with increasing dose. Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy reveal the formation of oxygen-containing groups accompanied by C═C bonds. By quantitatively correlating SMFS measurements with theoretical elasticities derived from quantum mechanical calculations, we provide the first single-molecule-level evidence that prolonged high-dose irradiation (2000 kGy) reconstructs the PVDF backbone into an alternating ether (C─O─C) and double-bond (C═C) architecture. This work establishes a direct link among irradiation dose, backbone transformation, and mechanical response, offering molecular insight into the irradiation regulation of PVDF for applications in extreme radiation environments.
