Most participants had not seen the control report (basic table of results). They were only given their results verbally. Most participants understood the meaning of the numbers in the control report and they were able to explain the meaning of various sugar levels values as well as knew what things (diet, physical activity, medicine, etc.) they should do in order to control their sugar levels. They were given this information when they visited the GP. No participants knew the meaning of the actual letters and numbers in the term HbA1C.
