Comparison between two groups was determined by the
Mann-Whitney test, t-test, or chi-squared test.
Parametric data were tested by Student's t-test, while nonparametric data were tested by
Mann-Whitney test. The percentage of females that released oocytes was analyzed by the test for difference between two proportions.
Mann-Whitney Test conducted between group 1 and group 2 exhibited statistically significant difference between two groups (U= 120; p = 0.001) in favour of group 1 (Mean rank = 41.50) compared to group 2 (Mean rank = 19.50) with more number of successful variables (Table 1).
Mann-Whitney test and Fisher's exact test were applied for data analysis.
Differences in medians between the groups were analyzed using the
Mann-Whitney test for non-normally distributed continuous or ordinal variables.
When the effect of irrigant regardless of the sealer was analyzed, saline had the highest immediate leakage rate that was significantly higher than that with DMSO (p=0.032;
Mann-Whitney test).
The Fisher's exact test and
Mann-Whitney test were used for comparative studies.
Intragroup and intergroup analyses were done using Wilcoxon signed ranked test and
Mann-Whitney Test respectively.
Since histograms showed that the FACT-G data was not normally distributed, a nonparametric (
Mann-Whitney test) statistical test was used to evaluate pairwise differences between sexes (Female, N=50; Male, N=29).
In Figure 3, age in both groups was presented and
Mann-Whitney test resulted in no statistically important difference between group I and group II.
