Coloured cells indicate statistical significance. The variable ‘time of measurement’ was included as one of the terms of the analysis of variance along with the variable of interest. The following variables were individually tested along with ‘time of measurement’: old age (>70 years), gender, FEV1 < 70%, DLCO < 70%, open surgery (as opposed to VATS). The dependent variable in each model was the QoL scale (i.e. SOB rest, SOB walk and so forth).

DLCO: carbon monoxide lung diffusion capacity; FEV1: forced expiratory volume in 1 s; QoL: quality of life; SOB: shortness of breath; VATS: video-assisted thoracoscopic surgery.
