The median duration of silica exposure was 15.5 years, and the majority were stone-cutters. DLCO and spirometry detected abnormalities in 72% and 52% of the study population, respectively. Notably, more than half (66.6%) of the participants with normal spirometry had impaired DLCO, recommending the addition of DLCO in the surveillance of silica-exposed workers. A significant correlation was observed between the duration of silica exposure and the severity of impairment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
