Results: In this study42 percent of patients presented with pulmonary manifestations. About 45.70 percent of the patients presented with abnormalities in the spirometry test, 42.85 percent showed HRCT abnormalities. The HRCT scores vary with age, TJC (Tender Joint Count), ESR, and SJC.FEV, 1 HRCT, and FCV showed a negative correlation among each other. However other variables did not show any statistically significant correlation. Conclusion: RA showed the prevalence of pulmonary affection, and this can be observed in pulmonary and radiological functions. There was an associationof age, pulmonary functions, and ESR.
