Table 2 Pulmonary function test values on the POD 1, 3 and 5, in percentage of the preoperative values.

From: Pleurotomy with subxyphoid pleural drain affords similar effects to pleural integrity in pulmonary function after off-pump coronary artery bypass graft

  1. p values refer to the difference of the FVC and FEV1 between groups. Data are shown as mean ± standard deviation. (FEV1 = Forced expiratory volume in 1 second; FVC = forced vital capacity; POD = postoperative day).
