Rational Design of Novel Isosteviol-Derived Factor Xa Inhibitors Using Integrated QSAR, Molecular Docking, Molecular Dynamics, and MM/GBSA Analyses.

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
Factor Xa (FXa) remains an important target in the development of anticoagulant and antithrombotic agents. In this study, twenty isosteviol-derived oxime ether analogs previously reported as FXa inhibitors were used to develop a predictive QSAR model. The compounds were geometry-optimized at the B3LYP/6-311++G(d,p) level, and Dragon molecular descriptors were calculated from the optimized structures. After descriptor filtering, Random Forest-based supervised preselection and correlation-based pruning were applied. Several models of increasing complexity were evaluated, including multiple linear regression, additive MARSplines, and constrained second-order MARSplines models. The final model employed four active basis functions involving R6p+, C-025, ATSC7e, and Mor31p and demonstrated excellent calibration and cross-validated predictive ability (R
