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

Lanthanide(III) complexes show diverse speciation in solution. Here, the photophysical properties and speciation in solution of binuclear lanthanide complexes bearing an aminophenolate chromophore that reversibly bind to both metal centers were determined. The aminophenolate can reversibly bind to both lanthanide ions in a pH dependent manner. Above pH 3 the phenolate moiety remains deprotonated and the lanthanide complexes exhibit very high kinetic stability, however, protonation of the amino group modulates the luminescence intensity without changing the luminescence lifetime of the lanthanide. Below pH 3, protonation of the phenol results in a flexible, open structure, leading to reversible demetallation of the lanthanide complex as the system comes under thermodynamic control. This study highlights the importance of a detailed understanding of both the speciation and pH responsive behavior of highly luminescent binuclear lanthanide complexes for their development as responsive probes. These results confirm the promise of phenolate derived binuclear complexes as highly luminescent responsive probes, modulated by changes in pH.
