Fig. 2.

Comparison between the first (T+6; blue bars) and second (T+12; red bars) follow-up period in terms of percent changes vs. baseline in injection habits, daily insulin doses, and hypoglycemic episodes (severe and symptomatic) within the only IG, showing that, despite analyzed parameters keeping the same decreasing trend, only LHSD decrease attained statistical significance (**p < 0.01). 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
