Table 2. Comparative measurement of side-to-side differences in length, width, and thickness of APL and AAPL (in mm).

		Side to side differences in length		Side to side differences in width		Side to side differences in thickness
APL	Right	68.2 ± 16.12	P value=0.955	5.7 ± 3.8	P value= 0.807	2.3 ± 0.9	P value= 0.23
	Left	67.9 ± 15.93		5.2 ± 4.0		2.5 ± 0.7
AAPL	Right	68.27 ± 19.6	P value= 0.941	2.7 ± 0.9	P value= 0.175	1.6 ± 0.4	P value= 0.001*
	Left	68.63 ±19.3		2.8 ± 1.2		1.3 ± 0.8
APL= abductor pollicis longus tendon
AAPL=accessory abductor pollicis longus tendon
*P<0.05 is statistically significant
