At Mammoth Cave National Park, White Nose Syndrome has affected the visitor procedures for entering and leaving the caves since the emergence of the disease in New York.
Multivariable analyses were then performed using logistic regression in which dichotomized expression levels of all miRNAs with excellent accuracy were included in a forward stepwise selection procedure (P<0.20 for entering and staying in the model) to determine the final predictors for the PDAC Signature Panel.
YTU-based standard operating procedures will be used for entering and checking data.
Furthermore, a backward conditional stepwise variable selection procedure was used, with P<0.05 for entering and P>0.1 for removing a variable in the model.
Other variables mentioned above besides computer use were included in the model based on a stepwise regression procedure with p = 0.15 for entering and p = 0.10 for remaining in the model.
Prognostic factors were selected using the stepwise procedure, specifying the significant levels for entering an additional explanatory variable into the model as 0.25 and for removing an explanatory variable from the model as 0.15.
Additionally, BMI, physical activity in leisure time at least once a week, computer use, alcohol use at least once a month, fish consumption, the logarithm of blood lead and the logarithm of serum PCB's 138, 153, and 180 were included in the model based on the stepwise regression procedure with p = 0.15 for entering and p = 0.10 for remaining in the model.
Additionally, we corrected for the covariates BMI of a child, physical activity in leisure time at least once a week, computer use, alcohol use at least once a month, fish consumption, the logarithm of blood lead and the logarithm of serum PCB's 138, 153 and 180, which were selected using a stepwise regression procedure with p = 0.15 for entering and p = 0.10 for remaining in the model.
