In Bioconductor/Icens: NPMLE for Censored and Truncated Data

Data on times to shedding of cytomegalovirus and to colonization of mycobacterium avium complex.

Description

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.

Format

This data frame contains the following columns:

cmvL

The left end of the CMV shedding interval.

cmvR

The right end of the CMV shedding interval.

macL

The left end of the MAC colonization interval.

macR

The right end of the MAC colonization interval.

Details

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.
