This paper discusses how randomized social experiments operate as an instrumental variable. For two types of randomization schemes, the fundamental experimental estimation equations are derived from ...

Table 1 Characteristics of SNPs considered for use in Mendelian randomization analysis of the effect of T2D on CHD risk. Figure 2: The Mendelian randomization estimate of the effect of T2D on CHD ...

Researchers have uncovered deep connections among different types of random objects, illuminating hidden geometric structures.

Of a variety of cancer types studied, researchers found that about two thirds can be chalked up to 'bad luck' -- random mutations that arise during DNA replication.

In this 13-week, multicenter, randomized trial, we randomly assigned in a 2:1 ratio persons at least 6 years of age with type 1 diabetes either to receive bionic pancreas treatment with insulin ...

Like all randomized clinical trials, our study was limited in terms of the generalizability of results to all patients with type 2 diabetes and coronary disease.

Dynamics and type of ESR1 mutations under aromatase inhibitor or fulvestrant combined with palbociclib after randomization in the PADA-1 trial.
