^aReactivity was considered low when the stimulation index (SI; counts per minute in the presence of antigen/counts per minute in the absence of antigen) of a TCC was between 2 and 10, intermediate when the SI was between 11 and 20, and high when the SI was >21. 

^bReactivity was high. 

^cReactivity was intermediate.
