QSPR modeling of some COVID-19 drugs using neighborhood eccentricity-based topological indices: A comparative analysis.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
COVID-19, which emerged in 2019, is a disease caused by a new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARSCoV-2), and has caused a worldwide epidemic. During and after this outbreak, it has been confirmed once again that finding a drug to prevent and end such diseases as soon as possible is an important issue. However, drug discovery and to determine a molecule's physical characteristics in a lab takes effort and time and is a costly process. Relevant information about molecules can be obtained by calculating topological indices, which are molecular descriptive numerical values corresponding to the physical properties of the chemical structure of a molecule. In this paper, we consider recently used drugs such as arbidol, chloroquine, hydroxy-chloroquine, lopinavir, remdesivir, ritonavir, thalidomide and theaflavin in treatment of COVID-19. This article examines neighborhood eccentricity-based topological descriptors that are used to analyze the structures of potential drugs against COVID-19. Eccentricity-based topological indices are advancing the field of chem-informatics and helping scientists better understand structure-activity correlations across a wide range of chemical compounds. The purpose is to identify structural components that have a significant impact on physico-chemical properties. In this context, the chemical structure and the corresponding molecular graph of the drugs under consideration are given in order to calculate the neighborhood eccentricity values. QSPR models are studied using linear and cubic regression analysis with topological indices for boiling point, enthalpy of vaporization, flash point, molar refraction, polar surface area, polarizability, molar volume and molecular weight properties of these drugs. Regression analysis is applied to find potential correlation between different drug characteristics such as bio-availability and efficacy. The results show that topological indices and applied regression models are useful in predicting significant characteristics of drugs used for the treatment of COVID-19. Additionally, a comparison of the known values and the calculated values from the regression models discussed is obtained.
