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

Tellurium, recognized as one of the technology-critical elements, should be considered as a xenobiotic. Its application, i.a. in the growing photovoltaic industry, raises concerns about Te(IV) and Te(VI) release to the environment. As both forms differ in mobility and toxicity, Te speciation should be included in water monitoring, but problems with speciation changes occurring during sampling, transport, and sample storage require the use of on-site separation of Te forms. A simple procedure based on solid phase extraction (SPE) with the anionic exchange mechanism (SAX, involving commercially available columns), followed by their quantification with elemental techniques, has a high potential for implementation in routine analysis. The proposed SPE-ICP-MS (inductively coupled plasma mass spectrometry) method allows direct analysis of Te(VI) and Te(IV), with Te(IV) determined after elution from the column. The detection limits obtained for the 5.0 mL sample are 0.02 ng mL
