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
Abl kinase plays a decisive role in the mechanism of the most fatal human pathogen chronic mylogenous leukemia (CML). Here, we have carried out a comprehensive study about the conformational flexibility, role of salt bridge and the protein- ligand interaction for this kinase with its well-known inhibitor, Imatinib. We have performed molecular dynamics simulations for conformational behavior, investigated the salt bridges and calculated the binding free energy of Imatinib with MM-PB/SA method for Abl kinase complex. We also explored the role of salt-bridge in the kinase complex and its effect on binding activity of inhibitors. Furthermore, to investigate the importance of those residues which form salt bridges, we mutated them by Alanine with the help of Alanine scanning program. We noticed significant variations in total free energy of Imatinib in all possible mutations. The binding free energy of ligand for kinase receptor was analyzed by molecular mechanics Poission Boltzmann surface area (MM-PB/SA) method. These results suggest that conserved glutamic acid and lysine are necessary for stability of complex.
