Table 2 Ultrasonographic findings of the pleural fluid and the pleura before and after pleurodesis

		Range	Mean ± SD
Amount of fluid drained (ml)		2000–5500	2815 ± 881.55
Duration of drainage (h)		1–3	1.65 ± 0.70
Estimated volume of pleural fluid (with US) 2 h after pleurodesis (ml)		0–100	33.25 ± 23.64
*PAS 24 h after pleurodesis		5–17	13.37 ± 2.87
		N (%)
**ASS 2 weeks after pleurodesis	A	10 (58.8%)
**ASS 2 weeks after pleurodesis	B	7 (41.2%)

*PAS Pleural Adherence Score: Pleural Adherence Score was scored in nine zones (upper, middle, and lower zones in the anterior, lateral, and posterior chest wall) across the affected hemithorax in real-time as present (= 0), questionable (= 1), or absent (= 2)
**ASS Absent Sliding Score: 2 weeks after pleurodesis—A (absent in more than 6 areas) and B (absent in 4 to 6 areas)
