About

Observational study about effect of the greatest Spanish heatwave over glycemic contro in adult patients with type 1 Diabetes mellitus.

Full description

Cross-sectional retrospective analysis of all patients with T1D in Castilla-La Mancha (south-central Spanish region) using intermittently scanned continuous glucose monitoring (isCGM). Glycometric data obtained through deidentified downloads from isCGM´s webpage. Primary outcome was time in range (TIR) 3.0-10 mmol/L (70-180 mg/d) change after the heatwave. 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.
