title: 'TTE: Design and Analysis Tools for Target Trial Emulation'
version: 1.1.2
doi: 10.32614/CRAN.package.TTE
abstract: Design and analysis tools for target trial emulation using longitudinal
  observational data. Functions are provided for checking person-period data, expanding
  longitudinal data into sequentially nested trials, estimating inverse probability
  weights for intention-to-treat and per-protocol analyses, and assessing weight distributions
  and covariate balance. Additional functions fit weighted pooled discrete-time outcome
  models, obtain standardized risks and treatment contrasts, and estimate weighted
  Kaplan-Meier and Aalen-Johansen curves. Two worked examples based on fully synthetic
  data illustrate an active-comparator new-user study comparing sodium-glucose cotransporter
  2 inhibitors with dipeptidyl peptidase-4 inhibitors and an analysis of sequentially
  nested trials comparing angiotensin receptor blocker and calcium channel blocker
  strategies.
