Odds of HP given associated correlates: multivariable backward analysis

HP	Odd ratio (95% CI)	P
BP (Y/N)	2.26 (1.36–3.76)	0.002
KP (Y/N)	5.73 (3.50–9.37)	<0.001
SRH (score)	0.57 (0.40–0.80)	0.001
Lower extremity power (W)	0.99 (0.98–1.00)	0.006
Trunk flexibility (cm)	1.17 (1.09–1.25)	<0.001
Hip abduction ROM (°)	0.94 (0.90–0.98)	0.005

Final model: Logistic Regression χ² = 159.40; Prob > χ² < 0.001; Pseudo R² = 0.2616. The initial fully adjusted model for HP also included: age, sex, weight, BMI, FP, depression, PM, physical activity last year, work activity age 20–60 and hip adduction ROM.
