Comparison of clinical parameters before and after intervention between VATS and streptokinase groups

Variable	VATS group (n = 28)	Streptokinase group (n = 18)	P-value
Before intervention:
Illness duration [days] mean ± SD	8.5 ±2.8	8.0 ±2.4	0.514^a
AB therapy [days] mean ± SD	6.3 ±2.2	7.3 ±2.2	0.140^a
After intervention
Hospital stay [days] mean ± SD	2.8 ±1.7	7.5 ±3.5	< 0.001^a
Days with fever [days] mean ± SD	1.9 ±0.7	3.0 ±1.6	0.017^a
Days with drainage [days] mean ± SD	3.0 ±1.6	7.5 ±4.4	< 0.001^a
Outcome, n (%):			0.042^b
Success	26 (92.9)	12 (66.7)
Failure	2 (7.1)	6 (33.3)

P-value of < 0.05 was considered statistically significant.
