3.6% of patients in the low-risk cohort had [less than or equal to]20% of PR positivity, while this ratio was 35% in the intermediate-risk cohort (Fisher exact test p=0.000).
Analysis indicated there was no statistically significant difference in the presence of six or more whorls between the breast cancer patients and control group (Fisher's exact test: [chi square] = 0.78, p = 0.500; p > 0.05) (Table 1).
In the template operative notes group 8/9 (written by junior residents) and 11/15 (written by senior residents) were found to be complete with a p-value of 0.61 (Fischer's exact test).

(p=0.009-Fisher's exact test) Also, these were found to be more freguent in children infected with HIV who are currently on HAART (p=0.013-Fisher's exact test).
With regard to familiarity with aphasia, there was a statistically significant difference in terms of occupation (p <.001, Fisher's Exact test), the level of education (p < .001, Fisher's Exact test), and the years of clinical experience (p < .001, Fisher's Exact test).
Patient age had no effect on the prevalence of metastases, as indicated by the results of [chi square]-test (p=0.796) and Fisher exact test (p=0.849) (Table 2).
Overall, the results are not statistically significant since the p-value is 0.543 (calculated by Fischer Exact Test) (Table-II).
The Fisher's exact test and Mann-Whitney test were used for comparative studies.
Categorical variables were compared using a Chi-square test or Fisher's exact test. Midterm survival was demonstrated by Kaplan-Meier survival curves.
