Patient Relevant Outcomes after total hip replacement. A comparison between different surgical techniques

Table 5 Univariate and multivariate logistic regression analysis comparing follow-up data (26–54 months) for SF-36 PF (physical function) and WOMAC function in patients operated on with hybrid or cemented technique (dependent variables) adjusted for age, sex, follow-up time and baseline values (explanatory variables) in the multivariate analysis.

variable	N	Multivariate OR	95% CI	p-value
Age	198	*0.59	0.46–0.76	<0.01
Sex	198	0.23	0.04–1.43	0.12
Follow-up time	198	0.90	0.79–1.02	0.10
WOMAC function baseline	196	1.00	0.95–1.06	0.90
WOMAC function follow-up	94	1.02	0.97–1.09	0.37

*per one year or scale unit increase. OR less than 1 means that with increasing age there is a less probability of being operated with hybrid technique. OR = odds ratio, 95% CI = 95% confidence interval
