Figure 2.

Acceptance of reward- and deposit-based incentive programs. Estimates are derived from a model that included the four interaction terms displayed and all covariates included in Table 1. Bars and shaded regions represent 95% confidence intervals. All interactions between incentive type (reward vs. deposit) and the patient characteristic (sex, race, annual household income, or months failed to pay bills) are significant at the prespecified threshold of P < 0.10.
