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

Within the expanding field of N-heterocyclic carbenes (NHCs) as surface ligands, this work investigates the etching of copper by (benz-)imidazol-2-ylidenes during surface functionalization. In order to control and distinguish between self-assembled monolayer (SAM) formation and NHC-mediated oxidative copper etching, experimental parameters were optimized. NHC design, concentration, solvent choice, temperature, visible light exposure, oxygen level, and deposition time dependencies were investigated, providing insight into the dynamic and sensitive interplay between functionalization and etching. Consistent with all experimental results, we present an etching mechanism driven by the formation of bis(NHC) Cu
