4–8	11.15 ± 4.28	13.37 ± 6.59	0.214
8–12	6.32 ± 5.09	7.13 ± 2.70	0.076
12–30	7.61 ± 5.01	7.89 ± 2.49	0.052
30–80	2.83 ± 2.48	4.35 ± 4.52	0.108
80–250	1.32 ± 2.89	2.54 ± 3.61	0.011
250–500	0.68 ± 1.18	1.45 ± 2.29	0.068

There was no significant difference after Bonferroni correction for multiple comparisons.
