Fig 1. Effusion levels of TNF-α, MMPs and their relationship with effusion radiological scores in TBP patients.

Levels of (A), TNF-α, (B), MMP-1 and (C), MMP-9 in pleural effusion of patients with TBP (n = 18) or CHF (n = 18), and the correlation between effusion levels of (D), TNF-α, (E), MMP-1 or (F), MMP-9 and effusion shadowing on chest radiograph in patients with TBP. TNF, tumor necrosis factor; MMP, matrix metalloproteinase; TBP, tuberculous pleuritis; CHF, congestive heart failure.
