Low Haemoglobin is Inversely Associated with Disease Activity in Rheumatoid Arthritis: A Cross-Sectional Study from a Tertiary Care Hospital

Extra-articular manifestations especially haematological abnormalities are common in Rheumatoid arthritis (RA). The aim is to study the haematological parameters and its correlation with disease severity and gender. A cross-sectional study was conducted at a tertiary centre among 50 RA patients who attended the Rheumatology or General Medicine OPD from January 2020 to June 2021.
