Background: Nonrandomized studies typically cannot account for confounding from unmeasured factors. Method: A method is presented that exploits the recently-identified phenomenon of “confounding amplification” to produce, in principle, a quantitative estimate of total residual confounding ...
cell lines generated from the same animal model and their wild type littermates, which implies a common, HD-related mechanism beyond immortalization artefacts. Overall, these findings argue for a thorough characterization of every cell line used and the inclusion of such confounding factors in the ...
Group matching refers to a similar process in which instead of individuals, groups are matched. Even if matching could eliminate the problem of population stratification, one potential problem is over-matching (that is, reduction of statistical power by unnecessary matching on too many factors, ...
(i.e., in which part of the sleep period CTmin occurs) [9,11,35,36,37,38]. More generally, CTmin is also easily confounded by factors such as posture, activity and arousal [39] and even in healthy individuals there appears to be interindividual variation in the relationship between CT...
