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

This work introduces a novel, cost-effective, and sustainable ionic liquid-assisted cloud point extraction (IL-CPE) technique for the enrichment and spectrophotometric quantification of trace copper(II) at 436 nm. The method employs the complexation of Cu(II) with (Z)-4-bromo-2-(((2-hydroxyphenyl)imino)methyl)phenol at pH 6.5, succeeded by extraction with 1-butyl-3-methylimidazolium hexafluorophosphate and Triton X-114. Under optimal circumstances, the approach exhibited remarkable linearity (2.0-300 µg L⁻¹, R
