Statistical association of different tissue biopsies (site specific pathology) among case-control groups.

Note: Statistical analysis showed 0 cells (0.0%) have an expected count less than 5 for all methods. The minimum expected count (MEC) for different methods were different, as the MEC for “a” is 48.01; “b” is 30.91 and “c” is 20.36. “d” denotes the use of a binomial distribution. Degree of freedom (df) was 1 (one) for all calculations. Data were considered statistically significant if p-value was less than 0.05. N: number of patients; n: number of samples; %: percentage.Statistical association of different tissue biopsies (site specific pathology) among case-control groups.
