SPARC identified as a prognostic marker in ILDs.
Strong expression in young fibrotic lesions; absent in older scars.
Study used spatial transcriptomics and cryobiopsy specimens.
Higher SPARC levels correlate with shorter overall survival.
SM2 module includes key genes like COL1A1, COL1A2, and COL3A
