Combine relative risks from air pollution and physical activity

Source: R/combined_rr_ap_pa.R
combined_rr_ap_pa.Rd

Combine relative risks (RR) from air pollution (AP) and physical activity (PA) through multiplication for diseases affected by both AP and PA

Usage

combined_rr_ap_pa(ind_pa, ind_ap, conf_int = FALSE)

Arguments

ind_pa

data frame of individual RRs for diseases affected by PA

ind_ap

data frame of individual RRs for diseases affected by AP

conf_int

logic: whether to include confidence interval from dose response relationships or not

Value

dataframe giving the RR risk for AP, PA and combined AP and PA exposure levels for every person in the baseline population and for each scenario

Details

This function performs the following steps:

  • join the ap and pa relative risk datasets

  • loop through all disease outcomes that are affected by both PA and AP:

    • for each scenario multiply the relative risks for PA and AP and store in a new column

    • if confidence intervals are required, multiply the upper and lower RR for AP and PA respectively wherever possible, otherwise use the given median RR values instead
