R code for the time-stratified meta-analysis of TAVR versus SAVR in low-risk aortic stenosis

This repository contains the R code used for the statistical analyses and visualization of a systematic review and meta-analysis comparing transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) in patients at low surgical risk. The code includes the primary RCT-only, observational/propensity-score-matched, and combined meta-analyses; time-stratified analyses of all-cause mortality; sensitivity analyses; Bayesian analysis; hazard-ratio analyses; GOSH diagnostics; secondary outcome analyses; publication-bias assessments; inter-rater reliability analyses; and risk-of-bias visualisations. The code accompanies the corresponding manuscript and is provided to support transparency and reproducibility. Local file paths and dataset names may require adaptation before execution. The underlying extracted study-level dataset is not included in this repository.
