The plot of the conditional and unconditional quantile regressions for medication possession ratio (adherence)

Note: The red line traces the conditional quantile regression (CQR) point estimates, while the blue line traces the unconditional quantile regression (UQR) point estimates. The light shade is the 95% confidence bands for the CQR estimates, and the darker shade represents the 95% confidence bands for the UQR estimates. The straight line at 0 helps assess the differences of the quantile effects from zero.
