Table 2.

Comparison of average SL width across the ab-/adduction and fist clench maneuver as well as the three measurement positions using linear mixed-effects models with post hoc Tukey tests. Only measurements from the first observer were considered. All models included the set of measurements (first or second) as fixed effect.

	Comparison of Average SL-Width

Both maneuvers
Medial vs. Proximal	−0.71	(−0.84, −0.58)	<0.001
Distal vs. Proximal	−0.64	(−0.78, −0.5)	<0.001
Distal vs. Medial	0.07	(−0.01, 0.14)	0.091
Ab-/adduction vs. Fist clench	−0.041	(−0.1, 0.018)	0.170
