(A): PCA results for exhaled breath samples from contralateral and ipsilateral lungs after surgery (4 components, R2X = 0.692, Q2 = 0.471). (B): PLSDA results for exhaled breath samples from contralateral and ipsilateral lungs after surgery (3 components, R2X = 0.486, R2Y = 0.952, Q2 = 0.815). (C): Y-intercepts for gas samples from contralateral and ipsilateral lungs after surgery: R2 = (0.0, 0.566), Q2 = (0.0, −0.435).
