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 depolymerization of condensed lignin-a byproduct of industrial pulping and biorefining-is crucial for sustainable biorefineries. However, it remains a formidable challenge due to the formation of recalcitrant C-C bonds during lignin isolation, restricting the reactivity and accessibility of the lignin macromolecule. Here, we demonstrate that a disordered crystalline mesoporous zeolite (Meso-Z) synergistically integrates strong acidity with enhanced mass transfer efficiency to process this bulk feedstock. Compared to conventional microporous zeolite, Meso-Z achieves 3.7-7.9 times higher yields (32.0-45.6 wt%) of aromatic monomers and dimers (MDs) from condensed lignin oligomers by C-C bond cleavage, thus enabling the total yields to exceed the theoretical maximum defined by C-O bond cleavage by 250-759%. Mechanistic studies reveal that this exceptional performance arises from Brønsted and Lewis acid-assisted hydrolysis and hydrogenolysis of C
