Analyses were conducted in SPSS, including descriptive statistics and frequency tables. During the second round, consensus was defined as 75% or more of panellists selecting ratings of 4 or 5, unless any panellist gave a rating of 0 (‘Not Valid’), 1, or 2. Additional response options included ‘Not Valid’ (coded as 0) and ‘Do Not Recall/Use’ (coded as missing). Cumulative percentages of ratings ≥4 were calculated to indicate overall agreement per statement.
