Table 1 Baseline characteristics of the study cohort. A total of 112,120 frontal chest radiographs were included, with 63,340 (56.5%) from male and 48,780 (43.5%) from female patients. On average, 0.72 ± 0.96 radiological findings were assigned per image, reflecting frequent co-occurrence of abnormalities. The most common findings were infiltration, pleural effusion, and atelectasis. Follow-up was defined as a metadata-derived proxy and operationalized as any recorded radiology encounter within 90 days of the index chest radiograph. No radiographs were excluded due to missing follow-up information.
