Fig. 1.

Comparison between the CG (blue bars) and IG (red bars) in terms of percent changes in injection habits, daily insulin doses, and hypoglycemic episodes (severe and symptomatic) occurring after the first 6-month follow-up with respect to baseline (pre-randomization period). All differences between the IG and the CG are statistically significant (p < 0.0001). NR, needle reuse; MR, missing rotation; CII,  cold insulin injection; ILHI, intra LH injection; DID, daily insulin dose; SeH, severe hypoglycemia; SyH, symptomatic hypoglycemia; LHSD, LH size decrease
