Sample size calculationPoisson and negative binomial models are frequently used to analyze count data in clinical trials. While several sample size calculation methods have recently been developed for superiority tests for these two models, similar methods for noninferiority and equivalence tests are not...
Sample size calculation for comparing two Poisson or negative binomial rates in noninferiority or equivalence trials Poisson and negative binomial models play an important role in clinical trials where count data are often analyzed. One of the main requirements to perform tests such as noninferiority ...

sample size calculations. We explore differences between the case-control and TND studies and identify the added variability relative to the case-control studies due to the random ratio of test-positives to test-negatives in the TND. We proposed a sample size calculation strategy for the TND to...

A quasi-likelihood negative binomial generalized log-linear model was built on the resulting data. In addition to the variable of interest (e.g. RCB), a batch effect, a DNA contamination effect (estimated by the percentage of intergenic mapping), as well as the age of the patients were ...
Full size image Fig. 9: IF-derived relative TH- and DAT-protein expression in TH-positive SN neurons. Plotted are the individual TH-positive neurons from Fig.8, according to their scaled x,y-coordinates, determined via DLAP-5, for all analysed animals (n = ~38500,N = 14). ...
While triple-negative breast cancer (TNBC) is known to be heterogeneous at the genomic and transcriptomic levels, spatial information on tumor organization and cell composition is still lacking. Here, we investigate TNBC tumor architecture including its
