Which statement regarding rheumatoid arthritis (RA) is NOT true? Joints are usually affected symmetrically. Many people with RA have rheumatoid factor in their blood. Early morning stiffness generally lasts less than 30 minutes. The joints most affected in the early stages of RA are the proximal interphalangeal joints (PIPs) and the metacarpophalangeal joints (MTPs).
