β-Zeolite-Assisted Lignin-First Fractionation in a Flow-Through Reactor*.
Article in ChemSusChem, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
In the present work, a hydrogen-free one-step catalytic fractionation of woody biomass using commercial β-zeolite as catalyst in a flow-through reactor was carried out. Birch, spruce, and walnut shells were compared as lignocellulosic feedstocks. β-Zeolite acted as a bifunctional catalyst, preventing lignin repolymerization due to its size-selective properties and also cleaving β-O-4 lignin intralinkages while stabilizing reactive intermediates. A rate-limiting step analysis using different reactor configurations revealed a mixed regime where the rates of both solvolytic delignification and zeolite-catalyzed depolymerization and dehydration affected the net rate of aromatic monomer production. Oxalic acid co-feeding was found to enhance monomer production at moderate concentrations by improving solvolysis, while it caused structural changes to the zeolite and led to lower monomer yields at higher concentrations. Zeolite stability was assessed through catalyst recycling and characterization. Main catalyst deactivation mechanisms were found to be coking and leaching, leading to widening of the pores and decrease of zeolite acidity, respectively.
