In syrona: Stratified Prevalence Comparison Across OMOP CDM Datasets
add_pr_columns R Documentation
Add prevalence ratio columns (log2 + natural + inference) to a data frame.
Description
Expects columns: prevalence_d1, prevalence_d2, denominator_d1, denominator_d2.
Usage
add_pr_columns(df)
Arguments
df
Data frame with prevalence and denominator columns.
Details
Formulas:
log2_pr = log2(p2 / p1)
SE(ln) = sqrt((1-p1)/(p1*n1) + (1-p2)/(p2*n2))
SE(log2)= SE(ln) / ln(2)
CI = log2_pr +/- 1.96 x SE
Value
Data frame with PR columns appended.
