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 effect of zeolite Y on the catalytic pyrolysis of polypropylene (PP) was investigated. In order to reduce the diffusion limitations related to the entry of reactants into and the removal of products from the zeolite cavities, mesoporosity was introduced via a surfactant-templating process. To further improve the catalyst efficiency in lowering the degradation temperature of the polymer and adjust the final product selectivity, two different amounts of calcium (CaO) or magnesium (MgO) oxides were loaded in the catalysts via incipient wetness impregnation. Three different silicon-to-aluminum (Si/Al) ratios (2.55, 15, 30) were tested, and the effects of the modifications on the degradation of PP were investigated. This systematic study proves the enhanced efficacy of the altered catalysts, underlining the synergistic relationship between mesoporosity, acidity, and the incorporation of alkaline-earth metal oxide in the catalytic pyrolysis of polypropylene. The successive modifications cause a significant reduction in the onset and degradation temperatures of the polymer while granting the tuning of the catalyst selectivity toward a narrower product distribution.
