TGFB1 and type 1 diabetes mellitus: Descriptive analysis of CD25high and TGFβ1 levels through 5 investigated groups (first-degree relatives of patients with T1D (FDRs) at stage 0, (FDRs0) and stage 1 (FDRs1) for development of T1D, patients with recent-onset T1D (R-T1D) in insulin-requiring state (IRS), patients in clinical remission of T1D (CR) and healthy controls (CTR)). Kolmogorov-Smirnov test showed the absence of normal distributions (all p values were under 0.001). The Man-Whitney test was conducted to detect statistically significant differences between observed categories.
