Table 3.

The differences between QUS parameters obtained with and without loading ( P values of Paired-Samples T-test)

Paired-Samples	Group 0	Group 1	Group 2	Group 3
wl_nBUA Vs. l_nBUA	p = 0.002^a	p = 0.007^a	p = 0.001^a	p = 0.009^a
wl_SOS Vs. l_SOS	p = 0.899	p = 0.024^a	p = 0.210	p < 0.001^a
wl_STI Vs. l_STI	p = 0.017^a	p = 0.270	p = 0.296	p = 0.126

The prefixes ‘l_’ and ‘wl_’ mean “loading” and “without loading”, respectively

^a There is significant difference between Paired-Samples.
