Association Between Continuity and Emergency Department Utilization, Stratified by Total Number of Primary Care Visits.

<p>AOR, adjusted odds ratio; CI, confidence interval.</p><p>*The adjusted odds ratio is the association between continuity and emergency department utilization based on the same covariates used in the model as outlined in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096356#pone-0096356-t003" target="_blank">Table 3</a>.</p

Adjusted Odds Ratio of Association Between ED Visit and Continuity of Care and Levels of Continuity.

<p>The first row illustrates the adjusted odds ratio between ED visits and continuity of care for individuals with at least one visit having continuity with their primary care provider. The second and third rows are the adjusted odds ratio for individuals who had high and medium levels of continuity and are compared to individuals with low levels of continuity, indicated by the asterisk (*).</p
