It should be noted that the SEER-based study has a tendency to be imbalanced in baseline characteristics, and propensity score matching (PSM) can be utilized to reduce the associated bias in this situation. The SEER data used in cohort, case–control, and case-series studies can be obtained...
. Measurement noise, understood as the random variability that produces a discrepancy between observed and true values (or repeated observations), is therefore tightly related to reliability as it contributes to error variance in the calculation of ICC. That is, a high level of noise results in l...

Reduce attrition in manufacturing. Learn how to stop first-day no-shows, early attrition, and later-stage turnover.
Here, we show that other methods, such as solely using the placebo control arm or calculation of a ‘proportional contextual effect,’ are limited and should not be applied. The aim of this study is to provide clear guidance on best practices for estimating contextual effects in clinical ...
In another research study posted on the Medical Science Monitor, the use of Listerine to reduce different types of harmful microorganisms was tested. The number of microorganisms drastically reduced after 5 minute exposure to both Listerine Freshmint and Listerine Cleanmint. This is another study that...

As compared with an ordinary Cox model, the TC models are shown to substantially reduce the bias of the estimated hazard ratio for treatment when data are simulated from a realistic Cox model with residual confounding due to the unobserved frailty. The simulations also indicate that the bias ...
Money can be tainted when it is associated with direct or indirect harm to others. Deciding whether to accept “dirty money” poses a dilemma because money can be used to help others, but accepting dirty money has moral costs. How people resolve the dile
