Table 1 The estimated knot value and standard error of the knot for each external load

From: Effect of external load on scapular upward rotation during arm elevation: the knot concept

Loads	Least mean square	Standard error	p-value
Unloaded	83.5	2.9	Reference
1 kg	81.2	2.9	0.33
2 kg	81.0	2.9	0.29
3 kg	76.1	2.9	0.01^a
4 kg	73.4	3.1	0.001^a
5 kg	75.8	3.1	0.02^a

^a: Indicate significance after Bonferroni corrections
The knot was defined as a point at which the scapular movement kinesiologically changed
