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

Tungsten-molybdenum (W-Mo) alloy are critical materials and widely used in aerospace and defense industries. During the manufacture, mechanical processing, and scrapping of W-Mo alloy products, a substantial quantity of waste W-Mo alloy is generated, which holds considerable importance for sustainable critical metals recycling and environmental protection. Hydrometallurgy treatment is demonstrated to be effective to address the multi-component metallic solid waste. However, the alloyed structure and strong chemical inertness of waste W-Mo alloys give rise to low recovery efficiency in conventional leaching processes. This study proposes an integrated ultrasound acid leaching - alkali leaching - solvent extraction process for the W and Mo separation from waste W-Mo alloy. First, the ionic form differences of W and Mo in acidic and alkaline media were investigated to lay the leaching and separation foundations. Thermodynamic calculation indicates that HNO
