Fig. 2

Measured and modelled DF, for models ICRP, NCRP, MPPD, and K&H. Subscript F denotes the modelled DF when keeping FRC at a fixed value, in this case 3.9 L (average of the group). Individual values are shown as circles. Lower and upper limits of each box represent 25th and 75th percentiles, respectively. Vertical bars at the end of lower and upper vertical bars represent 5th and 95th percentiles, respectively
