On-Surface Synthesis of Azobenzene-Linked Porphyrin Derivatives.
Article in The journal of physical chemistry letters, 2025. 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
On-surface synthesis has become an attractive strategy to obtain functionalized carbon nanostructures from small precursor molecules using a bottom-up approach. Although various on-surface reactions have been developed, it is still unclear how the chirality of self-assembled structures prior to reaction affects the coupling process. Here, we investigate homocoupling of nitro-phenyl groups in Pt-porphyrin derivatives on Au(111) surfaces using low-temperature scanning tunneling microscopy. Two different self-assembled structures composed either of linear oligomer of molecules of opposing chirality or of discrete trimers of molecules having the same chirality (i.e., homochiral) were respectively obtained by using differently substituted phenyl and 3,5-di-
