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
Polyelectrolytes currently play an increasingly important role in antivirus therapy. Antiviral activity towards influenza virus, measles virus, herpes simplex virus type 1, and cytomegalovirus was demonstrated for the 6000 Da polyelectrolyte polyallylamine. A nontoxic polyallylamine concentration of 30 µM at which the compound retains its antiviral effect towards measles and influenza viruses but lacks any toxic effect on human cells was previously determined. It is well known, at the same time, that simultaneous virus exposure to physical environmental factors and chemical substances causes a more significant decrease in virus infectivity. Temperature is among these physical factors since thermal exposure causes virus inactivation. Analysis of virus thermal inactivation parameters is of high practical importance when it comes to the development of vaccines against influenza virus and to the study of how virus particles infectivity decreases on various surfaces. In this view, the study of kinetic and thermodynamical characteristics of influenza virus thermal inactivation in the presence of the antiviral preparation polyallylanime is of particular interest. The paper reports that thermal inactivation of influenza virus in the temperature range of 38-60°C in the presence of polyallylamine follows the first-order reaction kinetics. Thermodynamic parameters of influenza virus thermal inactivation evidence that influenza virus surface proteins are involved in the inactivation process as a result of their interaction with polyallylamine. The obtained results show that polyallylamine may be used to accelerate thermal inactivation of the influenza virus.
