Appendix D. Statistical results of the secondary analysis of log-transformed mass-specific clearance rates for studies that employed a particle-uptake approach.
TABLE D1. Statistical results of the secondary analysis of log-transformed mass-specific clearance rates (mL·µg-1·h-1) for studies that employed a particle-uptake approach. Two sets of results are presented: for the complete data set (Complete, n = 274), and for experiments with acclimation times < 3 hours (No exhaustion, n = 188). NA, coefficients are not meaningful (dummy variables). NS, not statistically significant at P < 0.01.
