Exhaled breath analysis using volatile organic compound (VOC) profiling has emerged as a promising noninvasive approach for early disease detection. This feasibility study evaluated multicapillary column\/ion mobility spectrometry (MCC\/IMS)-based VOC profiling for differentiating silicosis from other respiratory conditions and healthy controls in an occupational health setting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a multicentre, cross-sectional observational study employing MCC\/IMS to identify VOC patterns.

Silicosis was distinguished from BARD and COPD with 100% and 87.5% accuracy (area under the receiver operating characteristic curve (AUC\n                      <jats:sub>ROC<\/jats:sub>\n                      ) 1.00 and 0.89), respectively.
