Multimorbidity and cardiovascular prevention in primary care: a cohort study in New Zealand.

Baseline dual therapy dispensing was 2.5%, 31%, and 40% in the low-, intermediate-, and high-risk groups, respectively.

Among participants receiving dual therapy at baseline, maintenance was higher among those with multimorbidity in the low-risk group (88% versus 84%) and intermediate-risk group (90% versus 86%) (both P <0.001).

In the high-risk group, maintenance was similarly high irrespective of multimorbidity (89% versus 88%; P = 0.412).
