We performed a sample size calculation in order to reduce the high yield of articles while maintaining a sample size capable of answering our research question.
To maintain as large a sample size as possible, we did not exclude controls (n = 114) whose matched cases did not meet the surveillance criteria.
However, sometimes it is not possible to maintain a certain sample size along the experimental design, especially in field studies.
We chose to sample these unconfirmed households at the same sites for zoonotic pathogens in their calves to maintain a rigorous sample size for prevalence estimates for the long-term study.
Even with access to a nationwide database, Seena Fazel, of the University of Oxford in the United Kingdom, and colleagues had to include a very diverse range of offenses, from rape to possession of child pornography and indecent exposure, to maintain a large sample size.
We determined cutoffs for the continuous variables of maternal age at birth and preceding birth interval to indicate early childbearing and short intervals, respectively, so that we could maintain a sufficient sample size for analysis and maximize the statistical significance of the model, while retaining consistency with the original purpose of the variable.
To maintain a robust sample size, we did not further consider cancers with fewer than 100 patient samples.
A set of six clusters was selected, as this solution most clearly identified distinct and nutritionally meaningful dietary patterns while maintaining a reasonable sample size in each group for subsequent regression analyses.
Firstly, our study maintains a large sample size and includes individuals from urban and rural settings in China, which allows for exploring the prevalence of obesity over a range of demographic groups.
