The estimates of the minimal important difference (MID) for the Saint George's respiratory questionnaire (SGRQ) score in CPA remain unknown. We performed a retrospective analysis on treatment-naïve CPA subjects (n = 148) treated with six-month oral itraconazole therapy and completed SGRQ at baseline and six months. The study's objective was to estimate the MID for SGRQ. We used an anchor-based method to determine the MID and found the MID for SGRQ of 7.3.
