Overview of the steps involved in the development of the SCCD

aThis article focuses on Stage 4: assessing the content validity of the SCCD. The preceding Stages 1–3 of SCCD development are briefly described in the Supplementary Information

bStage 2 clinical expert interviews were conducted with three clinicians who treat patients with RCC in order to understand the clinical practice experience of symptoms of RCC and to assess the concepts of interest identified in the literature review concepts. Relevant cough severity concepts were obtained and informed the development of the patient interview guide

cClinical expert feedback from one of the three clinicians in Stage 2 was also obtained on the SCCD Version 0.1 and Version 0.3 to assess the clinical relevance of the concepts included in the SCCD before the patient interviews
