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

Porphyrins possess one of the most robust aromatic circuits in chemistry, and even highly distorted derivatives preserve the intrinsic [18]π aromatic framework. Here we demonstrate that meso-strap engineering can override this intrinsic stability and induce controllable aromaticity redistribution within porphyrinoid networks. Systematic installation of tripyrrin-, 1,8-dipyrrylcarbazole-, and tetrapyrrolic straps reveals that short straps impose severe geometric strain that collapses the central [18] porphyrin aromatic circuit, generating alternative aromatic subunits or nonaromatic cores. In contrast, elongation to a tetrapyrrolic linker preserves the porphyrin aromaticity even in doubly bridged architectures. Structural, spectroscopic, and computational analyses collectively reveal that the intrinsic balance between strain energy and aromatic stabilization governs the fate of conjugation in these systems. These findings establish meso-strap engineering as a predictive design principle for controlling aromaticity redistribution in porphyrinoids and related π-conjugated macrocycles.
