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

Biogenic manganese oxides (MnOx) are promising agents for the removal and recovery of minor metals from water. However, cultivating heterotrophic Mn(II)-oxidizing microorganisms in non-sterile bioreactors remains difficult, and few continuous-flow reactor designs have been evaluated for their ability to recover minor metals under such conditions. In this study, we operated a laboratory-scale biofilm reactor packed with aspen wood and a polyurethane sponge for 469 d to evaluate its feasibility for biogenic MnOx production. Aspen wood served as a solid-phase organic substrate, the biodegradation of which provided a continuous release of soluble organic substrates to sustain the growth of heterotrophic Mn(II)-oxidizing microorganisms. The maximum mean dissolved Mn(II) removal rate by the reactor fed with artificial freshwater reached 3.0 mg L
