Highly Selective and Sensitive Detection of Hg(II) from HgCl2 by a Simple Rhodamine-Based Fluorescent Sensor.
Article in Journal of fluorescence, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
N-acryloyl rhodamine B hydrazide, a non-responsive control of a colorimetric Cu(2+) sensor, was used as a turn-on fluorescent sensor for Hg(II) from HgCl2 in the presence of AgNO3. The detection was highly selective and sensitive, and a large number of environmentally and biologically relevant metal ions, such as Na(+), K(+), Ca(2+), Mg(2+), Fe(3+), Cu(2+), Zn(2+), Cr(3+), Pb(2+), Ni(2+), Fe(2+), Mn(2+), Co(2+), Cd(2+), including Hg(II) from the easy dissociated salts, did not show significant interference. The fluorescence of the sensor (10 μM) was enhanced 74 folds by 10 equiv. of Hg(II) from HgCl2 in THF/HAc-NaAc (1/1, v/v, pH = 6) aqueous buffer solution containing 20 equiv. of AgNO3. The maximal fluorescence intensity increased linearly with the concentration of Hg(II) in the range of 0-70 μM. The detection limit of Hg(II) was 0.59 μM. The sensing mechanism was explored by Job's plot experiment, reversible experiment, mass spectrum analysis, spectroscopic analysis, and thin-layer chromatography.
