Stride-related rein tension patterns in walk and trot in the ridden horse

Table 2 Back-transformed least square means from the multivariable modeling of rein tension (N) in walk (data from 6 riders and 18 horses, n = 21,008 data points/208 normalised strides)

Variable	Category	LS mean	Group P value	Significant within-category
Rein	Left	12.5	0.67
	Right	12.8
Nose direction	In	12.3	<0.0001	c
	Out	12.9		c
Nose angle ROM (degrees^a)	<12	14.1	0.01	a	b
	≥12–16	13.8		a		b
	≥16–20	11.8
	≥20–24	12.9
	≥24	10.6			b	b

The model also contained the fixed effects of stride percentage (P < 0.0001) and its interaction with rein (P < 0.0001). If pair-wise comparisons within a variable were associated with P < 0.0001 this is marked with ‘c’, if 0.01 < P ≥ 0.0001 then ‘b’ and if P < 0.01 then ‘a’, these letters are indicated in both categories
^a The nose angle categories contained from top to bottom: 4747; 3939; 6666; 3434 and 2222 observations. Rein tension was modelled square root transformed, hence confidence intervals could not be produced on the back-transformed scale
