Towards personalized fluid monitoring in haemodialysis patients: thoracic bioimpedance signal shows strong correlation with fluid changes, a cohort study

Table 3 Correlation between the relative bioZ_R values at all frequencies in kHz and UFV. All correlations were statistically significant (p < 0.01). Correlation at 8 kHz was the highest compared to the other frequencies
