Early prediction of gait ability in patients with hip fracture

Table 5 Factors affecting gait prognosis: development of a prediction equation

	β	Standard error	p	Odds ratio	95% Confidence interval of odds ratio
	β	Standard error	p	Odds ratio	Lower	Upper
MAT	1.08	0.45	0.016	2.93^a	1.23	7.01
HDS-R	0.31	0.13	0.020	1.36^a	1.05	1.77
NYHA	−4.11	3.73	0.270	0.02^a	0.00	24.59
Const.	−12.9	5.01	0.010	0.00

−2ML (−2 maximal likelihood) = 16.71; Model X ² = 53.34 (P < 0.001)
Prediction equation: p = 1/[1 + exp(−1 × Score)]
Score = 1.08 × MAT(points) + 0.31 × HDS-R(points) − 4.11 × NYHA (category values of none = 0, mild = 1, severe = 2) − 12.9
^aIf the odds ratio > 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
