scrape_meta {ConfoundedMeta}  R Documentation 
Given relative risks (RR) and upper bounds of 95% confidence intervals (CI)
from a forest plot or summary table, returns a dataframe ready for metaanalysis
(e.g., via the metafor
package) with the logRRs and their variances.
Optionally, the user may indicate studies for which the point estimate is to be
interpreted as an odds ratios of a common outcome rather than a relative risk;
for such studies, the function applies VanderWeele (2017)'s squareroot transformation to convert
the odds ratio to an approximate risk ratio.
scrape_meta(.type = "RR", .est, .hi, .sqrt = FALSE)
.type 

.est 
Vector of study point estimates on RR or OR scale 
.hi 
Vector of upper bounds of 95% CIs on RRs 
.sqrt 
Vector of booleans (TRUE/FALSE) for whether each study measured an odds ratio of a common outcome that should be approximated as a risk ratio via the squareroot transformation
