From: Having a family doctor was associated with lower utilization of hospital-based health services

  2. *Statistically significant (p < 0.05) difference.
  3. †as reference category for doctor choice groups in logistic regression, Odds ratio <1 (less likely than the reference category), Odds ratio >1 (more likely than the reference category).
