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

The study evaluates biobased polyethylene (LDPE) structural changes induced by long-term thermal oxidation. The three grades of LDPE differentiated with structural properties were exposed to 90, 100, and 110 °C in an air atmosphere for 20 days. After aging, samples were comprehensively analyzed by Fourier transform infrared (FTIR) spectroscopy, focused on carbonyl group development, and quantified by the carbonyl index (CI). Detailed analysis, based on the deconvolution of the FTIR spectra, identifies each carbonyl compound, whose content varies depending on the structure of the LDPE. The changes in the crystallinity were investigated via X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The obtained results were supplemented by oxidation induction time (OIT), oxygen onset temperature (OOT), and an in-depth analysis of the rheological properties. The tested polymers undergo degradation with behavior similar to UV degradation of petrochemical ones, and the cross-linking process surpasses chain scission for samples degraded at 100 and 110 °C.
