TL;DR: In this paper, the authors investigated the association of early childhood undernutrition with physical and cognitive outcomes during preadolescent (8 to 11 years) years in 2011 to 2012 and found that being undernourished was associated with increased odds of short stature (odds ratio [1.73, 95% confidence interval [CI] 1.33 to 1.06) and thinness (OR 1.76, 0.63 to 0.82) during the pre-adolescent period.

TL;DR: This work addresses the problem of selecting the best linear unbiased predictor of the latent value of sample subjects with heteroskedastic measurement errors by comparing the usual mixed model BLUP to a similar predictor based on a mixed model framed in a finite population (FPMM) setup with two sources of variability.

TL;DR: The design and analytic approaches used by Ayers and colleagues do not appear to support the conclusions made in the paper, and a clear definition of outcome score thresholds for TKA selection at the individual patient level is needed.

TL;DR: Assessment for covariates will not result in more accurate prevalence estimator when ratio of male to female prevalences is close to one, sample size is small and risk factor prevalence is low, according to empirical guidelines.
