ACEI/ARB = antiotensin-converting enzyme inhibitors/antiotensin receptor blockers; CHC = community health center; FFS = fee for service; FHN = family health network; HbA1c = hemoglobin A1c; HSO = health service organization.

Note: Values, unless otherwise stated, are expressed as percentage of charts on which the individual manoeuvre was noted.

^aGenerated from contingency table using Pearson χ² statistic.

^bGenerated with analysis of variance.

^cResult of regression analysis with only model dummy variables.

^dP <.01 compared with CHC as reference.

^eP <.001 compared with CHC as reference.

^fP <.05 compared with CHC as a reference.

^gResult of regression analysis with model dummy variables and adjusted for patient age and sex.

^hPercentage of patients with HbA_1c ≤ 7.0

ⁱPercentage of patients with average target blood pressure in previous 6 months. Target blood pressure was 130/80 mm Hg for patients with diabetes and 140/90 mm Hg for all others.

^jP <.05 compared to HSO as reference.

^kP <.001 compared to HSO as reference.
