  1. The table shows mean values and standard deviations or absolute numbers. Column 2 and 5 show the results of comparisons between females and males irrespective of diabetes, significant (p < 0.05) differences are marked with (*). Column 3 and 6 show the results of comparisons between females and males without diabetes, significant differences are marked with (*). Column 4 and 7 show the results of comparisons between male and female diabetes patients, significant differences are marked with (*). Column 3 and 4 shows the results of the comparison between male non-diabetes and male diabetes patients, significant (p < 0.05) differences are marked with (°). Column 6 and 7 show the comparison between female non-diabetes and female diabetes patients, significant differences are marked with (°). The comparisons between groups were performed by unpaired t-tests, either for equal or unequal variances depending on the data, or by chi-square-tests in the case of categorical variables
