Title

strmst2 -- Postestimation command for strmst2

Syntax

strmst2pw indicator1
[, rmtl]
(Syntax 1)

strmst2pw indicator1 ReferenceIndicator
[, rmtl]
(Syntax 2)

Description

strmst2pw is a postestimation command that may be of interest after
strmst2 is run with the covariates option specified. strmst2pw
summarizes pairwise comparisons for the previously
estimated model. Three kinds of between-group constrast metrics (i.e. the difference
in restricted mean survival time (RMST), the ratio of RMST and the ratio of the
restricted mean time lost (RMTL)) are computed.

Syntax 1: Pairwise comparisons are summarized for the group
identified by indicator1 in reference to the group that was the reference
category in the previously estimated model.

Syntax 2: Pairwise comparisons are summarized for the group
identified by indicator1 in reference to the group identified by ReferenceIndicator.

Options

rmtl Display between-group contrasts for the ratio of the restricted
mean time lost (RMTL), in addition to the metrics for the restricted mean survival time
(RMST). The default is to show between-group contrasts only for the RMST.

Examples

Compare restricted mean survival time, specifying group 0 as the reference category:

. strmst2 treatment, tau(10) covariates(age bili albumin) reference(0)

Pairwise comparison of group 1 versus group 0 (the reference in the previously estimated model):

. strmst2pw _Iexarm_1

Pairwise comparison of group 1 versus group 2:

. strmst2pw _Iexarm_1 _Iexarm_2
