Development of a 96-Well Plate Dithiothreitol Method for the Colorimetric Determination of Nickel Ions in Water Samples.

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
A new, simple, and accurate assay was developed for the colorimetric determination of nickel ions in 96-well plates. The proposed method utilized the color change immediately visible even to the naked eye during the reaction of Ni(II) ions with dithiothreitol molecules (DTT). The intensity of the color produced by the formation of the complex between nickel and dithiothreitol is linearly proportional to the concentration of the metal ions in an alkaline environment, at room temperature, and the detection was performed using a mobile phone as the detector. The proposed method had a good linear response between 0.05 and 0.75 mmol L
