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 design and development of low-cost and efficient nonhomogeneous catalysts for silicon hydrogen addition is a hot research topic. This study reports the synthesis of a novel solid catalyst, PtCu-NVF-HBNC, derived from hazelnut shell biomass waste. The catalyst was prepared through carbonisation, nitrogen-doped activation, functionalisation with N-vinylformamide (NVF), and subsequent bimetallic Pt-Cu loading. It features a divalent platinum-vinylamine complex as the active centre. The introduction of Cu as a promoter induces competitive coordination with the Pt(II)-vinylamine complex, leading to electron density redistribution on the vinylamine ligand and a significant enhancement in Pt(II) coordination bond strength. This electronic modulation results in markedly improved activity and regioselectivity in the hydrosilylation of alkenes with tertiary silanes. The optimised catalyst, Pt
