However, you may have access to additional information which could be used to derive this value. In nQuery in these scenarios we provide side tables.
For example, in a one way analysis of variance using nQuery if we had three groups and we want to derive a value for the variance of means if we select the variance of means row the effects size side table will appear below the main table.
What Is The Appropriate Sample Size For My Study?
nQuery is the world’s most trusted clinical trial design platform. nQuery covers all phases (I - IV) and all types of trial designs (classical to adaptive).
Another example is in a group sequential table you'll be provided with a boundary plot which gives the boundaries of rejection for futility or efficacy at each time point.
Specify Multiple Factors
The specify multiple factors tool allows you to quickly and efficiently explore a number of scenarios in your sample size table.
for your sample size calculations
Event & Enrollment Prediction
nQuery Predict is the predictive module of the nQuery platform. It uses powerful modeling and simulation to accurately forecast your study duration. Model timelines for important trial milestones such as accrual and events. Identify roadblocks and take action to keep your trial on schedule.
