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

Nickel sulfate is a critical compound for lithium-ion batteries, mainly prepared from nickel sulfide concentrate (NSC). Typically, high-temperature smelting or high-pressure leaching is required to achieve high extraction rates for Ni and Co. Here, we demonstrate an acid-free atmospheric leaching process for effectively processing of NSC using a mechanochemical treatment. When a suitable intermediate phase of the NSC is obtained, the leaching efficiency for Ni and Co can reach 97.4% and 98.8%, respectively, while the main impure element, iron, almost remains in the solid phase. As a consequence, the leaching solution can be easily treated to prepare battery-grade NiSO
