Results of regression analyses (B values and OR) with p<0.05 as significance level, a three-level model.
Three level model: outcomes on patient level with age and gender as covariates; practice characteristics was the next level and country the third level. Country proved to be a significant factor in all analyses (p<0.0001, data not shown).
Primary analysis: practice level with two variables: (1) community resources and policies and (2) the Chronic Care Model composite score of the other five domains, comprising healthcare organisation, clinical information systems, self-management support, decision support and delivery system design.
Secondary analysis: practice level with two variables: (1) community resources and policies and (2) one of the other five domains: healthcare organisation, clinical information systems, self-management support, decision support or delivery system design. Only the estimates of these last domains are displayed in this analysis.
*Analysis found no estimate.
DBP, diastolic blood pressure; B, effect estimate in regression analysis; LDL, low-density lipoprotein cholesterol level; NS, not significant, significance level at p<0.05; SBP, systolic blood pressure.
