6. Fig E1
Study design and overview of the results. A, Schematic presentation of study design. B, Inserted table summarizes the number of biomolecules studied, not detected, changed, and unchanged in BAL fluid and serum from the study subjects. C, Number of biomolecules in BAL fluid that were significantly (P < .05) different among study populations.

7. Fig E2
Fold increase in biomolecule level in patients with RA compared with those with NRA (A and B). Patients with RA were subgrouped as having infection (infection positive, black bars) or no infection (infection negative, gray bars). Results in Fig E2, A, were separated from results in Fig E2, B, because of the higher level of increase (see labels on x-axis).
