AD	1.39	0.77	1.80	0.07	[−0.122, 2.907]
RD	0.10	0.79	0.12	0.9	[−1.449, 1.643]
RK	0.17	0.35	0.48	0.63	[−0.512, 0.846]
ODI	2.12	1.01	2.10	0.04	[0.145, 4.098]
NDI	−0.12	0.51	−0.24	0.81	[−1.117, 0.871]
AWF	−0.98	0.41	−2.42	0.02	[−1.775, −0.187]
Age^a	−0.72	0.51	−1.41	0.16	[−1.713, 0.279]

^a: represents no significant difference between the < 50 years old and ≥ 50 years old groups; ^b: positive numbers represent a positive correlation, negative numbers represent a negative correlation; ^c: represents the 95% confidence interval of the regression coefficient
