BCIS-PCI-relative-survival

R script to replicate analysis steps for study on relative survival in BCIS-PCI registry. Relies heavily on the tidyverse and on the relsurv package (see paper here)

Replication instructions

Run files in this order:

  • data preliminaries.R Loads relevant libraries, imports life-table data from ONS and processes BCI-PCI registry data.

  • models.R Stratifies data by year, sex, and indication and runs relative survival analysis on each stratum. Includes smoothed hazard over time + smoothed hazard ratio over age.

  • tables... .R and figures.R return tables and figures from objects created in first two files.

  • data synthetic.R creates synthetic BCIS-PCI registry data using methods from multiple imputation - see the sythpop package and accompanying paper. This allows the analysis steps to be replicated without disclosing real registry data (albeit providing different results).
