Appendix A. Statistical results of the secondary analysis of log-transformed individual clearance rates for studies that employed a particle-depletion approach.
TABLE A1. Statistical results of the secondary analysis of log-transformed individual clearance rates (mL·individual-1·h-1) for studies that employed a particle-depletion approach. Two sets of results are presented: for the complete data set (Complete, n = 135), and for experiments with acclimation times < 3 hours (No exhaustion, n = 99). NA, coefficients are not meaningful (dummy variables). NS, not statistically significant at P < 0.01.
