| Controls | T1DM total | T1DM < 5 | T1DM ≥ 5 | ||
| IMT LCA mean | 0.55 (± 0.04) | 0.56 (± 0.06) | 0.55 (± 0.05) | 0.57 (± 0.08) | 0.762* 0.737** 0.208*** |

IMT: intima-media thickness; LCA: left carotid artery; RCA: right carotid artery; Max: maximal.
* P values correspond to the comparison of the mean (± standard deviation [SD]) values in the entire T1DM group versus those in the control group. ** P values correspond to the comparison of the mean (±SD) values in the T1DM < 5 subgroup and those in the control group. *** P values correspond to the comparison of the mean (±SD) values in the T1DM ≥ 5 subgroup with those in the control group. The permutation test of Kruskal-Wallis was applied in the calculations. All results are expressed in mean (±SD) values.
