Comparative survival of five porcine reproductive and respiratory syndrome virus strains on six fomites.

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
Background and Aim: Despite the availability of vaccines, porcine reproductive and respiratory syndrome virus (PRRSV) continues to cause disease outbreaks in pigs worldwide. One of the reasons for this problem is the frequent mutation of the virus, which creates new variants. This study was conducted to determine the survival of five PRRSV strains on four non-porous and two porous fomites at 22-25°C (room temperature). Materials and Methods: Five strains of PRRSV (1-7-4, 1-8-4, VR 2332, 1-4-4 MN, and 1-4-4 SD) were used in this study. Circular pieces of aluminum, boot material, polyvinyl chloride, stainless steel, cardboard, and concrete were used as fomites. A small volume of each virus strain was placed on the fomite, followed by incubation at room temperature. The virus surviving at different time points was eluted in an eluent solution. Serial 10-fold dilutions of the eluate were inoculated in MARC-145 cells for virus titration. Multivariate analysis of variance (MANOVA) was used for statistical analysis, and Results: Three of the five strains were inactivated within 36 h on non-porous fomites; the remaining two survived for 72 h. On porous fomites, all five strains were inactivated within 12 h. MANOVA at p < 0.05 indicated that the inactivation of strains 1-7-4 and 1-4-4 SD was significant compared with the other strains. In addition, the number of virus titers was significantly reduced on stainless steel compared to other fomites. Conclusion: Our findings illustrate how the interaction between the PRRSV strain and fomite material affect viral stability over time. The results also provide an understanding of fomites' role in PRRSV epidemiology as indirect transmitters of the virus.
