  1. Notes: Data are presented as the median (25th, 75th percentile).
  2. *P < 0.05 vs. normal group. §P < 0.05 vs. T2DM with normal RVEF. The Kruskal-Wallis test was used to assess the differences in continuous variables among the three groups. DM, diabetes mellitus; RVEF, right ventricular ejection fraction; PS, peak strain; PSSR, peak systolic strain rate; PDSR, peak diastolic strain rate.
