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

Wastewater is nowadays increasingly receiving global attention as a resource much more than a problem due to its potential so serve as a resource recovery channel. In this regard, wastewater is gradually been transformed from being a cesspool to a "treasure pool." Among notable resources in the treasure pool, rare earth metals/elements (REEs) warrant focal investigation, both in terms of environmental abundance and biorecovery, due to their environmental impacts. The ineffectiveness or cost intensiveness of extant physicochemical and advanced wastewater resource recovery techniques warrants the investigation of natural phenomenons in the treasure pools. Bacteria are able to cleverly secrete certain biochemicals to help trap and aggregate nutrients for their metabolism-the biofilms. In this regard, there is increased espousal of biofilm-enabled reactors, especially for the application of the recovery of invaluable feedstock in wastewater as well as other aqueous media due to high production rates and stability of cells. Furthermore, it anticipated that this technology will be translated to recovery of rare earth elements, due to their increased demand across the globe. This piece reiterates the nitty-gritty of biofilm-enhanced biorecovery and also keeps the scientific readership abreast of the multifarious aspects regarding the successful biofilm affected biorecovery of REEs at reactor scale.
