Significant correlations between cytokines and spirometric data or cells in the post-TB airflow obstruction patients. a: Correlation between FEV1 and IL-1α; r = -0.286, p = 0,047. c: Correlation between FEV/FVC and IL-1α: r = -0.552, p = 0.003. d: Correlation between clinical stage and IL-17; r = 0.489, p = 0.013. e: Correlation between IL-6 and clinical stage; r = 0.401, p = 0.047. f: Correlation between TNF-α and FEV/FVC; r = 0.588, p = 0.007. g: Correlation between MIP-1α and lymphocytes; r = 0.4294, p = 0.0461. Legend: FEV1 = forced expiratory volume in the first second. FVC = forced vital capacity. IL = interleukin. MIP = macrophage inflammatory protein. r = correlation test. r = Coefficient of correlation: - When r is positive, this means that the concentrations of cytokine and the values of spirometric data (or the concentrations of cells) vary in the same direction. - When r is negative, this means that the concentrations of cytokine and the value of spirometric data (or concentrations of cells) vary in the opposite direction. p = significance threshold: - If p is greater than 0.05, the correlation is not significantly different. - If p is less than or equal to 0.05, the correlation is statistically significant
