     The 'cmv' data frame has 204 rows and 4 columns. The intervals
     should be treated as closed at both ends to replicate the analysis
     in Betensky and Finkelstein.

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _c_m_v_L The left end of the CMV shedding interval. 

     _c_m_v_R The right end of the CMV shedding interval.

     _m_a_c_L The left end of the MAC colonization interval.

     _m_a_c_R The right end of the MAC colonization interval.

     Betensky and Finkelstein, 1999 present data from the AIDS Clinical
     Trials Group protocol ACTG 181. This was a natural history
     substudy of a comparative trial. Patients were scheduled for
     clinic visits during follow-up and data was collected on the time
     until two events; shedding of cytomegalovirus (CMV) in the urine
     and blood and for colonization of mycobacterium avium complex
     (MAC) in the sputum or stool.
