Data were expressed as mean (95% confidence interval) and number (%).
Differences between groups tested with two-tailed students T-test for continuous parameters and proportions z-test for categorical parameters.
†Pack years data were available for 97 & 118 Indigenous Australian and Australian Caucasian subjects, respectively.
†This variable was non-parametrically distributed, thus displayed as median (interquartile range) and tested via equality of medians test.
*Denote statistically significant differences (p<0.05).
