Figure 2. Changes in channeling by covariate over study time periods (adjusted OR, 95% CI) comparing reciept of oxaliplatin with 5-FU.

Figure 2

OR=Odds Ratio; CI=Confidence Interval. Time periods are May through April of the years noted; time period specific estimates are from the calendar time-specific propensity score. Estimates for all years encompass May 2003-April 2006 and are from the conventional propensity score, adjusted for calendar time.

OR scale for CHF and Age at diagnosis is expanded due to wide confidence intervals or extreme values.

* Odds ratios are adjusted for all variables included in the propensity score

** Referent patients for diabetes, congestive heart failure and COPD are those without the condition

†Census median income modeled in quartiles as a continuous covariate, with highest income level as referent

¥Age modeled as categorical variable, with age group 65–69 as referent
