Fig. 6From: Effect of plasma sodium concentration on blood pressure regulators during hemodialysis: a randomized crossover studySDNN, LF/HF-ratio and BRS during hemodialysis. SDNN (upper panel; N = 11), LF/HF-ratio (middle panel; N = 11) and BRS (lower panel; N = 9) during hemodialysis (median and interquartile range). Abbreviations: SDNN: standard deviation of interbeat intervals (NN intervals); LF: low frequency; HF: high frequency; BRS: baroreflex sensitivity.
