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.
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
Coenzyme A (CoA) plays pivotal roles in a variety of metabolic pathways in all organisms. The biosynthetic pathway of CoA is strictly regulated by feedback inhibition. In the hyperthermophilic archaeon Thermococcus kodakarensis, ketopantoate reductase (KPR), which catalyzes the NAD(P)H-dependent reduction of 2-oxopantoate, is a target of feedback inhibition by CoA. The crystal structure of KPR from T. kodakarensis (Tk-KPR) complexed with CoA and 2-oxopantoate has previously been reported. The structure provided an explanation for the competitive inhibition mechanism. Here, further biochemical analyses of Tk-KPR and the crystal structure of Tk-KPR in complex with NADP(+) are reported. A mutational analysis implies that the residues in the binding pocket cooperatively contribute to the recognition of CoA. The structure reveals the same dimer architecture as the Tk-KPR-CoA-2-oxopantoate complex. Moreover, the positions of the residues involved in the dimer interaction are not changed by the binding of CoA and 2-oxopantoate, suggesting individual conformational changes of Tk-KPR monomers.
