↵3-150 In analysis A, each variable is adjusted for age alone. In analysis B, each variable is adjusted for all eight subject level variables: age, smoking, physical activity, BMI, alcohol intake, systolic blood pressure, cholesterol, social class, and height. The percentage of town variance explained is the percentage reduction in the variance for a model that includes the particular town level variable from that given for a model not including that town level variable.
