Because of our observation that COX-2 is an independent predictor of poor survival in ER-negative and HER2-positive breast tumors, we applied correlation and logistic regression analyses to examine the influence of both the tumor ER and HER2 status on the association between COX-2 and Akt pathway activation in 248 breast tumors.
Spearman correlation and logistic regression analysis assessed associations between positive blood cultures, mean subject whole-mouth percent radiographic crestal alveolar bone loss, and 100-day survival.
Correlation and logistic regression analysis identified several variables which were strongly indicative of the presence or absence of totara (Table 3).
Classification and Regression Trees (CART), Random Forest (RF) [40], multiple linear regression, correlation, and logistic regression analyses were carried out on untransformed data, whereas log-transformed data were used for t-testing.
Linear Pearson's correlation, partial correlation, and logistic regression analysis are used for analyzing relationships.
Correlation and logistic regression were used to identify and characterize observed associations.
Spearman's rank correlation and logistic regression models were used for correlation analysis and to calculate odds ratios (ORs), respectively.
Statistical analysis was performed using χ test, paired t-test, ANOVA, sample t-test, Pearson correlation, and logistic regression.
Relation of both scores on day 1 as well as last measured score before ICU discharge (T76x, T28x) with ICU/hospital LOS and ICU/hospital mortality was assessed with Pearson's correlation and logistic regression.
Correlation and logistic regression analyses suggest that this set includes beliefs that improving health and safety will make employees healthier and show that I care.
