**Figure 2.** **Telomere length and TSR correlate with acarbose use in T2DM patients.** Linear regression analysis of telomere length and age in the acarbose group (**A**) and the acarbose-free group (**B**); comparison of telomere length (**C**) and TSR (**D**) between the two groups. The solid lines in **A** and **B** indicate mean telomere length, calculated by regression analysis; y = -22.14*x+7362 in **A** (*r*=-0.45, *P* <0.0001) and y = -9.29*x+6756 in **B** (*r*=-0.15, *P* <0.05) (y = telomere length in bp and x = age in years). (**D**) TSR was -22.14 ± 4.66 bp/year for the acarbose group (n = 89) and -9.29 ± 4.30 bp/year for the acarbose-free group (n = 215). Telomere length is presented as the mean ± SD. TSRs are presented as the mean ± SEM. ns indicates *P* > 0.05, ****indicates *P* < 0.0001.
