Demographic characteristics of the study population
| VARIABLE | GROUP | Mean | S.D. | p-value |
|---|---|---|---|---|
|
AGE (years) |
A | 55,10 | 10,50 | 0,107 |
| B | 60,33 | 9,65 | ||
| C | 54,87 | 9,94 | ||
| D | 56,98 | 8,80 | ||
| TOTAL | 56,24 | 9,78 | ||
|
SEX (% males) |
A | 61,90 | NA | 0,081 |
| B | 77,80 | NA | ||
| C | 45,80 | NA | ||
| D | 50,00 | NA | ||
| TOTAL | 58,90 | NA | ||
| DURATION OF DIABETES (years) | A | NA | NA | 0,136 |
| B | NA | NA | ||
| C | 2,81 | 2,50 | ||
| D | 4,97 | 6,03 | ||
|
BMI (Kg/m2) |
A | 27,83 | 4,62 | 0,005 |
| B | 32,63 | 6,45 | ||
| C | 29,41 | 5,13 | ||
| D | 31,69 | 7,77 | ||
We used the Kruskal-Wallis test to analyze the variability of age, duration of diabetes & BMI and the chi squared test to analyze the sex variability between the 4 study groups. P-value found significant only for BMI, where the relative value of group A was significantly lesser than the correspondent of group B (p = 0,001) and group D (p = 0,002). All the other possible comparisons of BMI were found to be statistically insignificant. (NA = Not applicable)
