Any cases of serious bacterial infection missed because no tests were done and that resolved spontaneously within the follow-up time frame would not greatly benefit from earlier antibiotic administration.
We ruled out empyema when results of diagnostic tests were negative, or if no tests were performed because symptoms had disappeared, or were explained by another disease.
NA indicates that no tests were possible because the phylogenetic relationships potentially incongruent between the alternative topologies were not resolved in the focal topology.
Gene-doping could already be happening, and no one would know, because no test is yet on the horizon.
Studies in which the psychological intervention could not be distinguished from other elements of the intervention were also excluded (managed care interventions and disease management programs), as were studies in which a standardized effect size could not be calculated (mostly because no test was performed in which the difference between experimental and control or comparison group was examined).
"The CE mark isn't a product certification mark," Mr. Donaldson said, because no independent tests are required to get it; a manufacturer need only assert that the product meets applicable standards and take legal responsibility for saying so.
By selection no test was interrupted because of limiting side effects, and no test was positive for regional wall motion abnormalities.
However, because no cognitive tests were done in this study, our hypothesis was only supported by indirect evidence (i.e., Rasch and CFA models).
On the basis of the shedding pattern of individual cows, we developed a susceptible-infectious-recovered-susceptible (SIRS) transmission model with the following assumptions: (a) First lactation animals entering the herd as replacement animals were assumed to be susceptible (S) because no positive tests were found in any heifers leaving for the off-site facility or returning to the herd.
To reduce the number of parameters, we assumed that in the first time interval 1980 1983 all diagnosis rates are zero except for d5 because no diagnostic tests were available at that time and HIV could only be diagnosed when AIDS had developed.
