Identified discrepancies, if any, were resolved by reference to the source documents.; Following data entry verification, a first dataset was created in Excel. Data characterisation and quality checks were conducted to identify missing values, implausible values, and internal inconsistencies across questionnaire items. Predefined data cleaning rules were applied, in particular to address inconsistencies arising from skipping rules not respected by respondents.; The cleaned Excel dataset was independently quality checked by another FAMHP me
