Feature	SBM  n = 66	BBM  n = 87	TBM  n = 153	SMM  n = 45	BMM  n = 73	TMM  n = 118
Size, mm	10.56 ± 2.39	21.33 ± 4.94	16.68 ± 6.71	11.64 ± 2.08	22.60 ± 5.29	18.42 ± 6.89
SWV, m/s	1.82 ± 0.45g	2.18 ± 0.60	2.03 ± 0.57	3.66 ± 2.35b,c	6.74 ± 2.77d,e,f	5.57 ± 3.01a
AR	0.92 ± 0.20h	0.97 ± 0.21i	0.95 ± 0.21	1.46 ± 0.34k,l	1.43 ± 0.34m,n	1.44 ± 0.38j

Note: data are mean ± SD.

^a P < 0.001, compared with TBM.

^b,c P < 0.001, compared with SBM and BBM, respectively.

^d,e,f P < 0.001, compared with SBM, BBM, and SMM, respectively.

^g P < 0.001, compared with BBM.

^hFor SBM, n = 50, because ARs were unavailable in 16 masses of Pattern 2.

ⁱFor BBM, n = 64, because ARs were unavailable in 23 masses of Pattern 2.

^j P < 0.001, compared with TBM.

^k,l P < 0.001, compared with SBM and BBM, respectively.

^m,n P < 0.001, compared with SBM and BBM, respectively.
