The following metrics were used in analyses: ever/never probably exposed; highest level ever probably exposed; and duration of probable exposure (in years) at medium or high level.
To acknowledge the skewed distributions of exposures of nurses to antineoplastic agents [ 17], and to ensure that only those with reasonable possibilities of exposure were attributed exposure-time, a multiplicative weighting (0.00, 0.0625, 0.25, and 1.00) was assigned to the exposure probabilities from the algorithm (none, unlikely, possible, and probable exposure, respectively).
Positive responses were followed by further questions about the probability of exposure (i.e., no exposure, possible exposure, or probable exposure) by nursing position (i.e., supervisor/coordinator, clinical nurse specialist, head nurse/unit manager, charge nurse, staff nurse) and year.
For each of the relevant exposures, we combined women who reported definite or probable exposure for estimation of RRs and considered women unexposed if they reported probably not or definitely not.
The plant manager from Brentwood also came by the hospital, Mr. Richmond said, and together they talked through the events of his probable exposure -- all of which pointed to a case of simple bad luck.
Even though conventional vaccines have been relatively successful against influenza A infection, the ability of adenoviral vectors to rapidly generate a strong immune response may be useful to specific applications such as rapid immunization of health care workers in anticipation of a probable exposure to an emerging virulent pandemic virus such as H1N1-1918.
Associations with fibroids were generally consistent for definite and probable exposure, except associations with in utero DES exposure and maternal gestational diabetes, for which associations were much stronger with reporting probable exposure.
Probable exposure misclassification could have biased estimates in either direction, and the number of subjects was modest.
The delay between probable exposure and onset of symptoms was 3-10 days (mean ± standard deviation 6.1 ± 1.9 days).
Post-exposure prophylaxis was the use of oseltamivir after probable exposure to influenza but before symptoms developed.
An important aspect is that people rarely become infected from foxes, thus the most probable exposure is through dogs.
