Get population attributable fraction — get

This function calculates the population attributable fraction (PAF) of a health outcome due to exposure to an environmental stressor

Usage

get_paf(rr_at_exp, prop_pop_exp)

rr_at_exp: Numerical value Risk estimate of the concentration response function for a specific concentration. The population attributable fraction is normally calculated using the risk estimate that refers to the concentration that reflects the population exposure and the cut-off. This risk estimate is obtained after re-scaling from the epidemiological study with a particular increment (e.g. for PM2.5 10 or 5 ug/m3) to the aimed concentration.
prop_pop_exp: Numeric value or numeric vector specifying the population fraction(s) exposed for each exposure (category). Default: 1. See Details for more info. Only applicable in RR pathways.

This function returns the population attributable fraction as a numeric value.
