“…Compared with HRCT, a predictive score based on sex, age at RA onset, RA Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28‐ESR), and the MUC5B rs35705950 risk allele had 75% sensitivity and 85% specificity for identifying RA‐ILD (15), but this tool may be difficult to apply in clinical practice. A risk score based on sex, smoking status, extraarticular manifestations, a clinical disease activity index score, and ESR had 90% sensitivity and 64% specificity for identifying RA‐ILD (49). A model based on sex, smoking status, rheumatoid factor, C‐reactive protein, and matrix metalloproteinase‐3 had a C‐index of 0.826 for accuracy to detect RA‐ILD compared with assessment by a multidisciplinary team (50).…”
