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

The traditional combustion-chlorination distillation process used for extracting germanium (Ge) from lignite not only causes significant environmental pollution but also wastes the high-value humic substances (HSs), especially fulvic acids (FAs) in lignite. This study attempts to comprehensively recover Ge, humic acids (HAs), and FAs from lignite using an alkali extraction-acid precipitation-chlorination distillation (AEAPCD) method. The optimized process parameters are obtained as alkali extraction at 100 °C for 2 h using 0.3 mol/L NaOH as the extractant and a liquid-solid ratio of 9:1, acid precipitation of extracted liquid using HCl to adjust the pH value to 1, and the chlorination distillation of Ge-rich FA solution at 95 °C for 30 min. In this case, the recovery yields of HAs and FAs in their respective products are 88.83 and 91.42%, respectively, and the Ge recovery yields of GeCl
