| Dyspnea 12 | YES | YES | |
| UCSD-SOBQ | N/A | YES | |
| Cough | Leicester Cough Questionnaire | YES | YES |

CTD-ILD: connective tissue disease–related interstitial lung disease; IPF: idiopathic pulmonary fibrosis; MRC: Medical Research Council Dyspnea Scale; YES: consensus was met; UCSD-SOBQ: University California San Diego Shortness of Breath Questionnaire; N/A: consensus was not met; HRQoL: health-related quality of life; SGRQ: St. George’s Respiratory Questionnaire; VAS: Visual Analogue Scale; PROM: patient-reported outcome measures; SSc-ILD: systemic sclerosis–related interstitial lung disease; PtGA: Patient Global Assessment.
It is important to recognize that at this time of the recommendations several PROM instruments currently used today had not yet been developed and that for this study SSc-ILD was the prototype CTD-ILD.
