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
The crystal structure is reported of p-hydroxybenzoate hydroxylase (PobA) from Pseudomonas putida, a possible drug target to combat tetracycline resistance, in complex with flavin adenine dinucleotide (FAD). The structure was refined at 2.2 Å resolution with four polypeptide chains in the asymmetric unit. Based on the results of pairwise structure alignments, PobA from P. putida is structurally very similar to PobA from P. fluorescens and from P. aeruginosa. Key residues in the FAD-binding and substrate-binding sites of PobA are highly conserved spatially across the proteins from all three species. Additionally, the structure was compared with two enzymes from the broader class of oxygenases: 2-hydroxybiphenyl 3-monooxygenase (HbpA) from P. nitroreducens and 2-methyl-3-hydroxypyridine-5-carboxylic acid oxygenase (MHPCO) from Mesorhizobium japonicum. Despite having only 14% similarity in their primary sequences, pairwise structure alignments of PobA from P. putida with HbpA from P. nitroreducens and MHPCO from M. japonicum revealed local similarities between these structures. Key secondary-structure elements important for catalysis, such as the βαβ fold, β-sheet wall and α12 helix, are conserved across this expanded class of oxygenases.
