Study summary

Observational cross-sectional multicenter study about clinical efficacy of insulin pumps in type 1 diabetes mellitus patients.

Read the detailed description

Observational cross-sectional multicenter study about clinical efficacy of continuous subcutaneous insulin infusion in type 1 diabetes mellitus patients.

All clinical variables are gathered from the Spanish Insulin Pump National Registry.

Data analysis is conducted using SPSS (Chicago, IL) statistic software. Results are presented as mean +/- SD values. 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.
