At least for the artificial insemination centres considered in this study, no significant effect of commercial semen on PRRSV transmission was found for neither ORF5 nor ORF7.
Furthermore, when all patients were considered together, there was no significant effect of rituximab on synovial content of any of the autoantibodies or immunoglobulin studied, with the lone exception of IgG heavy constant region message 8 weeks following rituximab infusion.
Considering surface EMG parameters, no significant effect of Time or Group was found on median frequency slope of all measured muscles.
2. During spontaneous variations in heart rate, rate was correlated positively with right ventricular output (P less than 0.0001) and end-diastolic dimension (P less than 0.0001) among the lambs considered as a group, but no significant effect of rate on stroke volume was found.
In this population there was also an epistatic interaction between two new loci on chromosomes 4 and 5; these new loci had no significant effect considered separately (Fig. 3).
The method was considered robust, since no significant effects occurred for the response describing the quantitative aspect of the method.
This model was chosen because when including breed as a random effect (here, breeds are considered as samples within each species) no significant effect was observed and because the model minimizes both Akaike Information AICC) and Bayesian Information (BIC) Criteria (see Additional file 1: Table S1).
In all the other cases, the null hypothesis (H1) was accepted (there was no significant effect of the considered factor or interaction).
In other words, in the Results section, any p value lower than 0.05 is considered a significant effect.
The results from EDTA and citrate plasma were each compared to those measured in serum, and if there was a significant (p < 0,05) difference this was considered a significant effect of anticoagulant.
