When there were modest differences between advice groups, we tested for confounding and found no evidence.
To compare postoperative respiratory data and pulse oximetry between the two groups, we tested the null hypothesis (H0) that postoperative pulse oximetry values are comparable.
To investigate the phenotypic differences between domesticated and wild groups, we tested the amount of time spent heading toward a human hand, the amount of time spent contacting a human hand and the time spent jumping.
In addition to the tests on the differences between the intervention and control groups, we tested the intervention group for differences in empowerment, experienced knowledge, anxiety, and depression levels from baseline to after the empowerment strategy.
To test for differences between groups, we used t-tests for continuous variables and the chi square test or Fisher's exact test for categorical variables.
Accordingly, to compare distributions between groups, we used T-test, non-parametric Kruskal-Wallis test or chi-square test.
To estimate the differences between groups, we used Student t test, χ test, or Fisher exact test, as appropriate.
For comparison between groups, we used t-test and Chi-square statistics as needed.
For non-parametric tests of differences between groups we used the Kruskal Wallis test for continuous variables and χ test for categorical variables.
To test the statistical significance of differences between groups, we used the χ test or Fisher's exact test for categorical variables and analysis of variance (ANOVA) for continuous variables.
