Comparisons between UPCF and Each Assisted PCF (n=51)

Data are expressed as mean ± SD (liters/min).

UPCF, unassisted peak cough flow; PCF, peak cough flow; MPCF, manual assisted peak cough flow; PCFmic, peak cough flow under maximum insufflation capacity; MPCFmic, manual assisted peak cough flow under maximum insufflation capacity.

^*p < 0.01.

^†Both the values of MPCF and PCFmic, which were similar, were higher than that of UPCF but lower than that of MPCFmic.
