Correlation between glucose transporter mRNA expressions and echocardiographic parameters registered prior to sample procurement. a Correlation between left ventricular (LV) end-diastolic diameter (LVEDD) and LV sodium-glucose cotransporter 1 (SGLT1) relative mRNA expression. b Correlation between LV ejection fraction (EF) and LV SGLT1 relative mRNA expression. c Correlation between LVEDD and LV facilitative glucose transporter 1 (GLUT1) relative mRNA expression. d Correlation between LV EF and LV GLUT1 relative mRNA expression. e Correlation between LVEDD and LV GLUT4 relative mRNA expression. f Correlation between LV EF and LV GLUT4 relative mRNA expression. The color of dots corresponds to that of Fig. 1 according to the subgroups. For zero-order correlation analysis, Spearman’s rho (rs) was computed. For all correlation coefficients, bias-corrected and accelerated (BCa) 95% confidence intervals (CI) are reported based on n = 1000 bootstrap samples.
