Table 3.

Table showing the operative outcomes after stage two redo completion lobectomy. The use of NSAID was significantly associated with reduced risk of severe pleural adhesions and complete pleural symphysis, but not operative time, blood loss, persistent air leak and post-operative length of stay. For pleural adhesions, the result was presented in terms of absolute risk and the 95% confidence intervals. p-value was obtained from the one-sided Boschloo's test. (Note: the primary outcome “severe pleural adhesions and complete pleural symphysis” were denoted as “pleural adhesions” in the table for simplicity).

	Treatment: with NSAIDa (N = 27)	Control: without NSAID (N = 17)	p-Value
Pleural adhesions (absolute risk and 95% confidence intervals)	0.19 (0.04–0.33)	0.47 (0.23–0.72)	0.03
Operative time (minute)	157 ± 21	173 ± 21	0.86
Blood loss (mL)	131 ± 50	152 ± 15	0.72
Persistent air leak	7 (25.9%)	7 (41.2%)	0.15
Post-op length of stay (day)	5.8 ± 1.1	6.4 ± 1.5	0.72
