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

Designing of fluorophores for multifarious optical applications is a fascinating area of research. We report the photophysical behaviour of a synthesized coumarin based probe (E)-N'-(1-(7-(diethylamino)-2-oxo-2 H-chromen-3-yl)ethylidene)-4-hydroxybenzohydrazide (CP) and its utility as a cell-imaging agent. CP exhibits emission from monomers and J-aggregates in solution. The spectrodynamics in the solid-state, on the other hand, was dictated by contributions from H- and J-aggregates along with the monomers. CP showed good emission aptitude in aqueous solutions at pH value 7.0, which is close to the biological pH (7.35-7.45). The emission aptitude of CP in water was utilized to use CP as a cell imaging agent. To our delight, CP can successfully image human peripheral blood mononuclear cells (PBMC) with the cell matrix showing prominent green and red emission at the respective channels observable under a fluorescence microscope. Furthermore, we probed the binding nature of CP to PBMC cells by the aid of molecular dynamics simulations.
