Table 3 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.

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

variable N Univariate OR 95% CI p-value
Age 198 *0.62 0.53–0.72 <0.01
Sex 198 0.52 0.28–0.97 0.04
Follow-up time 198 0.99 0.96–1.02 0.49
SF-36 PF baseline 196 1.00 0.98–1.02 0.98
SF-36 PF follow-up 196 *1.02 1.00–1.03 <0.01
WOMAC function baseline 196 1.02 0.99–1.05 0.16
WOMAC function follow-up 94 *1.02 1.00–1.04 <0.01
  1. *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
