Forest plots demonstrating regression coefficients (β) and corresponding 95% confidence intervals for significant associations between biomarkers and measures of cardiac autonomic function in type 2 diabetes mellitus patients. Associations which were independent of the influence of any co-variable are presented. IL-6: interleukin-6; IL-18: interleukin-18; hsCRP: high sensitivity C-reactive protein; TP: total power; LF: low frequency power; NO: nitric oxide; eNOS: nitric oxide synthase; HF: high frequency power; RMSSD: root mean square of successive differences between adjacent R-R intervals; pNN50: percentage of N-N intervals that vary by more than 50 ms; 30/15 ratio: ratio of 30th and 15th R-R interval during head-up tilt test
