On the one side, selection of patients for the interviews might be biased towards individuals with milder disease who are capable to undergo an interview procedure.
All statistical tests will be one sided.
On one side, natural selection should favor mothers who limit the nutritional costs of pregnancy and have more offspring; on the other, it should also favor fathers whose offspring maximize the nutrients they receive during gestation, setting up a direct conflict.
The base-case and the SAs demonstrate that on the one side a careful selection of reliable input-data is important, but on the other side a wide range of SAs has to be conducted to reduce uncertainty within model results.
The bar, housed in a sprawling old garage with 25-foot ceilings, is lined on one side with an excellent selection of quarter-operated video games from the '80s.
The purpose of this analysis was to investigate the effect of a one-sided selection process based on the statistical significance on the false-positive rate in meta-analysis in situations where publication bias detection methods cannot not identify the bias.
The simulations were restricted to one-sided selection depending on the p-value for the hypothesis that the true underlying effect is zero.
The aim of this analysis was to study whether a one-sided selection process based on the statistical significance threatened the validity of those meta-analyses where no evidence of publication bias was apparent.
The scenarios with publication bias (RR=4 and RR=10) provide estimates of the power of different tests to detect a one-sided selection process based on the statistical significance.
The results of these realistic simulations demonstrate that when a one-sided selection process based on the statistical significance is present, the false-positive rate in meta-analysis dramatically increases.
