Study summary

Observational retrospective study about effectiveness and safety of insulin Faster Aspart on continuous subcutaneous insulin infusion treated adult Type 1 Diabetes Mellitus (T1DM) patients in routine clinical practice.

Read the detailed description

Cross-sectional retrospective analysis about effectiveness and safety of insulin Faster Aspart on continuous subcutaneous insulin infusion treated adult Type 1 Diabetes Mellitus (T1DM) patients in routine clinical practice.

All clinical variables are gathered from two EMR softwares (Mambrino XXI and Carelink Pro®).

Data analysis is conducted using SPSS (Chicago, IL) statistics software. Results are presented as mean ± SD values or percentages. A paired Student's t-test or a Wilcoxon signed-rank test were used for the analysis of differences. Comparisons between proportions were analyzed using a chi-squared test. A P value \< 0.05 was considered statistically significant.

The protocol was approved by the reference Castilla-La Mancha Public Health Institute Ethic Committee. All participants provided written informed consent.
