Principal component analysis of EIM measurements in young and aged zebrafish. Nine EIM parameters were used in this analysis (phase: 2, 50, and 250 kHz; reactance: 2, 50, and 250 kHz; and resistance: 2, 50, and 250 kHz). Data from 51 animals was used (n = 27 young, i.e., 8 months, and n = 24 aged, i.e., 36 months). The first two components of the PCA explained 86.2% of the variance between the young and aged zebrafish. The EIM parameters of phase at 2 kHz phase, resistance at 2 kHz resistance, and reactance at 2 kHz, 50 kHz, and 250 kHz contributed to >80% of PC 1. Resistance at 50 kHz and 250 kHz and phase at 50 kHz and 250 kHz contributed to >80% of PC 2.
