Statistical analysis
Descriptive statistics were used to characterize the basic features of
the data in the study. We compared the features of patients who had
contributory tests to those who had non-contributory ones. We used the
Chi-square test and Fisher’s exact test for categorical variables, and
the T-test and Mann Whitney U test for continuous variables, as
appropriate. A p-value of less than 0.05 was considered significant in
all the tests. Parameters found to be significantly associated with
contributory results of PET/CT (true positive) on univariate analysis
were analyzed in a multivariate analysis using forward step logistic
regression analysis.
