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

In this study, gold and silver were recovered through a bioleaching process conducted at room temperature over 11 days. Native bacteria and varying ratios of mineral pulp to culture medium (20/80, 37.5/62.5, and 50/50 %) from a mining operation in Zacatecas, Mexico, were evaluated. The mineral was crushed to a particle size of 0.125 inches or smaller, containing gold and silver concentrations of 0.609 g/ton and 138.89 g/ton, respectively. Four native microorganisms were identified using molecular biology techniques and a 16S rRNA gene fragment:
