3. Fewer than three swollen metacarpal-phalangeal joints

3. Fewer than three swollen metacarpal-phalangeal joints or participants do not meet the criteria for rheumatoid arthritis

(would remove this number "5" as this is not one of the criteria used in Dillon's NHANES study. The text was put here to compare with ACR criteria. No such data available from NHANES III
