Data presented as bias (lower and upper LoA) and Lin's concordance correlation coefficient (ρc). Reference values developed by Oostveen et al. [16] were considered as the standard model and these were compared with other reference values for R5, R20 and X5. Bias and LoA should be read as a percentage (e.g. a bias of 0.15 should be read as 15%). #: resistance and reactance values measured at 6 Hz (R6, X6) and 19 Hz (R19) were considered in the comparison; ¶: resistance value at 19 Hz (R19) was considered in the comparison. R5: resistance at 5 Hz; R20: resistance at 20 Hz; X5: reactance at 5 Hz; AX: reactance area; LoA: limit of agreement; NA: not applicable.
