did not reach statistical significancep = 1.0000
The length of stay in the intervened group (those requiring pleural intervention) was 8.8 days (1–25 range) as compared to 6.75 days (2–12) in the observed (those not requiring pleural intervention) group; however, this did not reach statistical significance. {95% CI (−7.3629 to 3.2629), p = 1.0000}.
