Table 1 Description and explanation of variables included in the analysis

From: Which patient and treatment factors are related to successful cardiovascular risk score reduction in general practice? Results from a randomized controlled trial

Variable* Explanation
Dependent variable:  
ΔSCORE (%) Estimated 10-year cardiovascular mortality risk according to SCORE** after one year minus estimated 10-year cardiovascular mortality risk at baseline (negative numbers indicate a decrease in estimated risk)
Independent variables:  
Patient characteristics:  
Sex (male/female) n (%) male Sex of participant
Age (years) Mean (SD) Age of participant
Level of education (4 levels) n (%) Self-reported highest level of education of participant
SCORE at baseline (%) Mean (SD) Estimated 10-year cardiovascular mortality risk according to SCORE** at baseline of participant
Treatment characteristics:  
Treatment group (control/intervention) n (%) interv. Treatment group into which participant was randomised: with (intervention group) or without (control group) self-monitoring
Consultation time (minutes) Mean (SD) Total duration (in minutes) of all visits to practice nurse in the framework of the SPRING study
Treatment intensity (%) Mean (SD) % of indicated treatment goals for which treatment had actually been started
Home blood pressure device Was a home blood pressure device used as part of the SPRING study?
Home weighing scale Was a home weighing scale used as part of the SPRING study?
Home pedometer Was a home pedometer used as part of the SPRING study?
More than one visit for smoking Was smoking cessation discussed at more than one visit to the practice nurse?
New/changed medication for cholesterol Was medication for cholesterol newly prescribed or the dosage altered?
New/changed medication for hypertension Was medication for hypertension newly prescribed or the dosage altered?
  1. *The independent variables are described in the following manner: variable (description of categories/unit of measurement) n (%) category/Mean (SD), except for the variables with categories yes/no: these are not described any further and the given results are n (%) of “yes”.
