1. Calculate the amount of change and rate of change in itching VAS, visit 1 vs. visit 2/3 for outpatients, comparison at hospitalization for hospitalization vs before discharge. The t test of correspondence is carried out for the verification. From the results, the subjects are classified into a group with improved itching and another group.
2. Cross tabulate the background factors related to the differences between the groups and search for items with significant differences in the chi-squared test.
3. Consider the involvement of confounding factors and conduct multiple logistic analysis as a sub-analysis.
4. Analyze the presence or absence of correlation between each evaluation result and evaluate with Pearson correlation coefficient and significance level.
