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

Direct lithium extraction (DLE) represents an emerging technology with considerable potential for lithium recovery from low-grade brines. Nonetheless, DLE still faces several unresolved challenges, particularly concerning the purity of the resulting lithium eluates. The DLE eluate obtained in this study contained approximately 3600 mg/L Li, 2350 mg/L Ca and 1200 mg/L Na. Sorbent-based purification is regarded as one of the most efficient methods for eluate treatment. Among sorbents, titanium phosphates, zirconium phosphates, and zirconium aminotris (methylenephosphonates) are known for their high sorption capacities toward various metal ions. Therefore, this study aimed to develop a zirconium-titanium phosphate-phosphonate sorbent capable of removing impurities from DLE eluates. As a result, a novel powdered ZrTiPO
