Diaphragmatic excursion data are shown as median and first and third quartiles (error bars). Preoperative, 2 h and 24 h after operation diaphragmatic excursion in the video assisted thoracoscophy (VATS) and in the thoracothomy group. #P = 0.007 between groups after 2 h; *P < 0.0001 between groups after 24 h. Pairwise comparisons were adjusted using Bonferroni correction.
