Multilevel Poisson regression model*: rates ratios (95% CIs) for the effects of access to PCP on the rate of office visits stratified by tertiles of geographic availability of orthopaedic surgeons, Ontario: 2007–2008
| Geographic availability of orthopaedic surgeons (thirds of the distribution) | |||
|---|---|---|---|
| Lowest | Middle | Highest | |
| Access to primary care physicians | |||
| Quintile V (highest) | 1.50 (1.02 to 2.21) | 1.29 (1.03 to 1.63) | 0.85 (0.59 to 1.22) |
| Quintile IV | 1.16 (0.90 to 1.51) | 1.17 (0.92 to 1.47) | 0.95 (0.65 to 1.37) |
| Quintile III | 1.17 (0.99 to 1.64) | 1.11 (0.78 to 1.30) | 0.89 (0.62 to 1.27) |
| Quintile II | 1.12 (0.90 to 1.39) | 1.19 (0.94 to 1.50) | 0.86 (0.58 to 1.28) |
| Quintile I (lowest) | 1.00 | 1.00 | 1.00 |
