Percent of study population with poor adherence and poor control by disease duration and age.

In other words, the longer a patient has diabetes, the poorer his control may be. Furthermore, as the duration of having diabetes increases, poor adherence to medication decreases; so medication adherence is stronger among those who have had diabetes longer. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0108145#pone-0108145-g002" target="_blank">Figure 2b</a> demonstrates that as the age group of patients with diabetes increases, both poor control of the disease and poor medication adherence decreases. In other words, control and adherence are stronger among the older age groups.
