It has also been observed that the time elapsed since diagnosis of diabetes was higher among insulin-dependent patients compared to non-insulin-dependent patients, with a mean of 18.37±9.01 years and 13.53± 9.4 years, respectively (p = 0.007). Significant differences were found in a study that sought to identify the same relationship in patients over the age of 30 (9.6±9.2 years for insulin-dependent patients and 6.0±6.1 years for non-insulin-dependent patients, with p = 0.043) .
