Statistical methods / analysis
Quantitative analysis will involve trend analysis over time and chi-squared tests to determine the association between demographic factors and non-participation reasons. A p-value of less than 0.05 will be considered statistically significant. Qualitative analysis will involve thematic analysis of patient narratives to extract meaningful patterns and themes regarding reasons for non-participation.
