Table 1 DJ-1's correlations and associations

Variable	Spearman's rho	Correlation P-value	Linear regression R^2	Association P-value
SOD1	−0.476	0.002	0.150	0.022
8-Isoprostane	−0.264	0.033	0.113	0.040
Pleural fluid LDH	−0.497	0.001	0.292	<0.0001
Total cell count	−0.325	0.041	0.124	0.032

SOD1: (copper–zinc) superoxide dismutase-1; LDH: lactate dehydrogenase; Ns: non-significant.
