Hypertension, diabetes, myocardial infarction, heart weakness, stroke, kidney disease, cancer (excluding white skin cancer), lung diseases and musculoskeletal diseases were addressed. Self-reports and GP reports, overall agreement, over-reporters and under-reporters are shown as totals and in percentages. Specific positive and negative agreement is shown in percentages. All parameters were calculated as shown in figure 2. Total n varies due to missing values.
COPD, chronic obstructive pulmonary disease; GP, general practitioner.
