Results

Age- and sex-specific reference ranges for CT-derived TLV in healthy Caucasian adults were calculated with following equations: 

For the predicted TLCct median and variability respectively in males: exp(-17.2472+0.0853 * log[age] + 3.5829 * log[height]); exp(9.8+0.471*log[age] + -2.539*log[height]). 

For females: exp(-12.2016+0.05813 * log[age] + 2.6292 * log[height]); exp(-2.7115+-0.5220*log[age] + 0.6064*log[height]).

Wormplots for both males and females show in the y-axis deviations from the theoretical normal distribution. Our dataset shows a slight curvature, which suggests minor deviations from normality with points remaining within the confidence bounds, indicating that the normality assumption is reasonably met.
