Reproducibility bundle: scale-dependent effect modification of physical activity by multimorbidity (HRS and CHARLS)

Analysis code and machine-readable result files for a target trial emulation of moderate-to-vigorous physical activity and all-cause mortality in the Health and Retirement Study and the China Health and Retirement Longitudinal Study. Contains the twelve-script chain that regenerates every reported number from the raw data, together with the full set of exploratory variants (1,471 scripts, 81 result files). Intermediate serialised objects are not archived because the build scripts regenerate them from the raw data.
