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 manuscript describes a simple and reliable method for direct solid sample analysis applied for Cu determination in powdered fish samples using line-source graphite furnace atomic absorption spectrometry. Direct solid sample analysis was performed using a laboratory-made device based on glass capillary tubes for sample mass measurement and transportation to the graphite furnace. The pyrolysis and atomization temperatures were optimized; the optimum conditions were achieved at 1100 °C (pyrolysis) and 2400 °C (atomization). External calibration against aqueous solutions proved to be a reliable alternative for Cu quantification in fish samples with good accuracy. The detection and quantification limits for Cu determination in fish tissues were 0.04 ng g
