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
Bordetella pertussis, the causative agent of whooping cough, is an opportunistic virulent bacterial pathogen that is resistant to a wide range of antibiotics due to a variety of resistance mechanisms. Looking at the increasing number of infections caused by B. pertussis and its resistance to diverse antibiotics, it is essential to develop alternative strategies to fight against B. pertussis. Diaminopimelate epimerase (DapF) is an important enzyme of the lysine biosynthesis pathway in B. pertussis that catalyzes the formation of meso-2, 6-diaminoheptanedioate (meso-DAP), which is an important step in lysine metabolism. Therefore, Bordetella pertussis diaminopimelate epimerase (DapF) becomes an ideal target for antimicrobial drug development. In the present study, computational modelling, functional characterization, binding studies, and docking studies of BpDapF with lead compounds were carried out using different in silico tools. In silico prediction results in the secondary structure, 3-D structure analysis, and protein-protein interaction analysis of BpDapF. Docking studies further showed the respective amino acid residues for ligands in the phosphate‑binding loop of BpDapF play a vital role in the formation of H‑bonds with these ligands. The site where the ligand was bound is a deep groove, which is regarded as the binding cavity of the protein. Biochemical studies indicated that Limonin (binding energy - 8.8 kcal/mol), Ajmalicine (binding energy - 8.7 kcal/mol), Clinafloxacin (binding energy - 8.3 kcal/mol), Dexamethasone (binding energy - 8.2 kcal/mol), and Tetracycline (binding energy - 8.1 kcal/mol) exhibited promising binding towards the drug target DapF of B. pertussis in comparison with the binding between other drugs and act as the potential inhibitors of BpDapF that eventually can reduce the catalytic activity of BpDapF.
