Diagnostic role of interleukin -33 in the differentiation of pleural effusions especially tuberculous and malignant effusions

Table 5 Comparison between serum IL-33 levels in each studied groups

Effusion	Range	Mean	Paired “t.”	P
Serum IL-33 in TPE N = 36	12.46–15.11	13.90 ± 0.85	6.73	> 0.05 (NS)
Serum IL-33 in MPE N = 33	15.21–20.32	13.50 ± 1.98	6.73	> 0.05 (NS)
Serum IL-33 in Parapneumonic group N = 24	5.23–7.21	6.22 ± 0.76	20.5	< 0.001 (HS)
Serum IL-33 in transudative group N = 24	5.38–6.67	6.10 ± 0.42	23.9	< 0.001 (HS)

TPE Tuberculous pleural effusion, MPE malignant pleural effusion
This table shows that serum IL-33 is significantly higher in tuberculous pleural effusion than of parapneumonic and transudative pleural effusion groups. However, there was no significant difference between serum IL-33 in tuberculous and malignant groupse
