The weighting schemes are shown as Gene Expression Domain Weighting/Clinical Covariate Domain Weighting/Indicators of Disease Status Domain Weighting. Column 2 shows the percentage of subjects correctly classified by asthma status after assigning asthma status based on the majority of subjects in the group. Column 3 shows the number of asthmatic and non-asthmatics groups respectively using this definition. Entries in bold represent those methods showing at least 65% accuracy. Information on the classification accuracy of the individual asthmatic clusters for these methods is shown in Table 8.
