Early prediction of gait ability in patients with hip fracture

Table 6 Statistical data and prediction equation using MAT evaluated after 1 week (MAT-1w)

	β	Standard error	p	Odds ratio	95% Confidence interval of odds ratio
	β	Standard error	p	Odds ratio	Lower	Upper
MAT-1w^a	1.26	0.57	0.027	3.53^b	1.15	10.79
HDS-R	0.43	0.23	0.063	1.53^b	0.98	2.40
NYHA	−6.28	4.70	0.182	0.00^b	0.00	18.87
Const.	−17.1	7.54	0.024	0.00

−2ML (−2 maximal likelihood) = 12.54; Model X ² = 53.87 (P < 0.001)
Prediction equation: p = 1/[1 + exp(−1 × Score)]
Score = 1.26 × MAT-1w(points) + 0.43 × HDS-R(points) − 6.28 × NYHA(category values of none = 0, mild = 1, severe = 2) − 17.1
^aMAT-1w is motor age test that evaluated after 1 week from initiation of weight-bearing exercise in a rehabilitation room
^bIf the odds ratio is > 1, the probability categorized into walking group is higher as the point is larger; if the odds ratio < 1, the probability categorized into non-walking group is higher as the point is larger
