Effects of Adjusting for Instrumental Variables on Bias and Precision of Effect Estimates

Recent theoretical studies have shown that conditioning on an instrumental variable (IV), a variable that is associated with exposure but not associated with outcome except through exposure, can increase both bias and variance of exposure effect estimates. Although these findings have obvious implic...
