Considering the distribution of the test-negative design data, the score test approach based on multinomial distribution can be an alternative for the sample size determination. Finally, we have framed the problem as a hypothesis test to assess whether VE > 0% or relative VE > 0% (...

This distinguishes sample-size determination for survival studies from that for other studies in which the endpoint is not measured as a time to failure. intro — Introduction to power and sample-size analysis 7 All the above leads us to consider the following two types of survival studies. ...
formulae, might be useful for retrospectively computing power once a trial has commenced (and thus the size has been determined), and will also be useful in those limited number of studies for which the trial sample size is indeed completely fixed (for example within a cohort study) [9, ...
score sample size to account for additional variability in the ratio of controls over cases. This work enhances our understanding of the data generating mechanism in a test-negative design (TND) and how it is distinct from that of a case-control study due to its passive recruitment of ...
The recent emergence of multi-sample multi-condition single-cell multi-cohort studies allows researchers to investigate different cell states. The effective integration of multiple large-cohort studies promises biological insights into cells under differ
