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

Herein, multifunctional fluorescent N-doped carbon dots (N-CDs) are synthesized from O-phenylenediamine and 4-aminobenzoic acid. Hydrothermal synthesis and nitrogen doping make the N-CDs possess good physical and chemical properties with bright emission at 567 nm (QY = 32%) and present obvious excitation dependence. Among common metal ions, only Cr(VI) strongly and linearly decrease the yellow fluorescence of N-CDs in wide concentration ranges of 20.0-180 µM and 180-350 µM. Thus, N-CDs are constructed as efficient fluorescence probe for Cr(VI) with detection limit of 1.94 µM. The mechanism of quenching is indicated as the inner filter effect (IFE). The proposed sensor has been successfully applied in two kinds of water samples. In addition, the CDs are tried to apply for cell imaging. Above experiments prove that N-CDs based sensors are efficient strategies for sensitive Cr(VI) detection and cell imaging.
