NIST Polymer Pyrolysis Search: A New Pyrolysis GC-MS Search Program and Mass Spectral Reference Library.
Article in Environmental science & technology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Pyrolysis is the thermal decomposition of a material in an inert environment and is used in combination with gas chromatography-mass spectrometry (py-GC/MS) for analyzing the chemical composition of a wide variety of organic materials. The identification and deconvolution of polymers, including mixtures with complex matrixes using a searchable mass spectral library of individual pyrolysis products (pyrolyzates) is presented. It is demonstrated that this method can successfully identify components in polymer mixtures, including polyolefins, a mixture of polymers that have secondary reactions during pyrolysis, a copolymer as distinct from homopolymers of its individual components, and a polymer within a complex biological matrix (with a prepyrolysis in situ hydrolysis and methylation step). The resulting interactive, freely available search software application and pyrolysis reference library for the qualitative identification of polymers is described.
