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

Polycyclic aromatic hydrocarbons (PAHs) are widespread pollutants and especially difficult to degrade under anoxic conditions. The non-substituted three-ring PAH phenanthrene is activated through carboxylation to 2-phenanthroic acid which is then ligated to Co-enzyme A to produce 2-phenanthroyl-CoA, followed by step-wise reduction of the aromatic rings. The first reduction reaction is catalyzed by 2-phenanthroyl-CoA reductase producing dihydro-2-phenanthroyl-CoA. In this study, we elucidated the second reductase enzyme in the pathway, catalyzing the reduction of dihydro-2-phenanthroyl-CoA to hexahydro-2-phenanthroyl-CoA. Dihydro-2-phenanthroyl-CoA reductase (AprC) was heterologously overproduced in
