Efficient design for Mendelian randomization studies: subsample and 2-sample instrumental variable estimators.

abstract：:In the spring of 1986, the authors studied the relation between body mass index and anthropometric indicators of fat distribution to cardiovascular risk factors (serum lipids and blood pressure) in approximately 450 women aged 38 years randomly selected from population registers in five European centers. Waist circumf...
