π-Enlargement in Porphyrin Macrocycles at Interfaces.
Article in Angewandte Chemie (International ed. in English), 2026. 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
Porphyrins are essential heteroatomic macrocycles, fundamental to both biological systems and advanced technology. Their unique molecular architecture enables key functions in nature, such as oxygen transport in hemoglobin and light harvesting in chlorophyll, and inspires cutting-edge applications in chemical sensing, catalysis, renewable energy conversion, and optoelectronics. Consequently, significant efforts are dedicated to develop their solution-phase chemistry, particularly by strategically modifying the macrocyclic structure to tailor their properties. Inspired by the field of on-surface covalent synthesis, we introduce a pioneering strategy to tailor porphyrin macrocycles at interfaces, specifically expanding an 18-π porphyrin into a 20-π system. Such transformation is achieved by depositing a porphyrin precursor, equipped with two trifluoromethyl (-CF
