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

Spent petroleum catalyst as a repository of several toxic metals is recommended for metal removal before safe disposal. To evaluate an effective biotechnological approach for metal removal, a comparative study between sequential-aerobic and sequential-anaerobic bioleaching processes was conducted for the removal of metals from crushed-acetone-pretreated spent petroleum catalyst. The SEM-EDX and XPS analysis confirmed the presence of Ni, Al, Mo and V in their oxidic and sulphidic forms in spent catalyst. The bioleaching experiments were performed in stirred tank batch reactors (2.5 L), temperature 30 °C, pH 1.4 and stirring speed 250 rpm for the period of 160 h. Sulfuric acid acted as lechant for both sequential-aerobic ( SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12088-021-00978-8.
