Comparison of hierarchical cluster groups of cytokine concentrations in RSV and non-RSV induced AOM

Group	Non-RSV AOM* (N = 129)	RSV AOM** (N = 16)
1	2 (1.6%)	2 (12.5%)
2	66 (51.2%)	3 (18.8%)
3	2 (1.6%)	0 (0%)
4	59 (45.7%)	11 (68.8%)

The groupings are based on the cluster pattern identified in Figure 1;

Figures in parenthesis indicate percent of the column total;

^*Non-RSV group included 49 cases of other viruses, and 80 cases with no virus identified;

^**RSV versus Non-RSV groups, p = 0.011 (Chi square analysis)
