QMVC – quadriceps maximum voluntary contraction, FFM – fat free mass, SNiP – sniff nasal pressure, PEmax – maximum expiratory pressure, FEV1 – forced expiratory volume in one second, TLCO – carbon monoxide transfer factor, FRC functional residual capacity. Mean (SD). There was no significant difference at baseline between patients who were or were not followed up at one year. *p < 0.05 vs baseline.
