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.

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

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
  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
