FIGURE 2

Immunization coverage and number of doses administered over the course of the study. A, Median immunization coverage over the course of the study period in the control (white square), automated mobile phone reminders alone (white triangle), and automated reminders with compliance-linked incentives (black triangle) groups are shown. The dotted line represents the overall rates. Immunization coverage is defined as the proportion of the total number of immunizations received divided by the total number of immunizations required for each child at the time of measurement. B, We show the cumulative number of doses administered from the time of enrollment in the control (brown), automated mobile phone reminders alone (purple), and automated reminders with compliance-linked incentives (green) groups.
