  nQuery Advanced-样本大小和功效软件

Sample size for fixed to flexible clinical trials

In 2018, 91% of organizations with FDA approved clinical trials used nQuery for sample size calculation.

Receive Regulatory Approval

Consistently calculate the correct sample size for FDA/EMA submission

  • Validated sample size tables & procedures
  • Sample size statement generator
  • Automated installation & operational qualification procedures (IQ/OQ)

 

Reduce The Risk & Cost of Trials

Bayesian & Adaptive techniques to optimize your trial design

  • See how likely it is to receive a 'positive' outcome from your trial through the Bayesian module in our sample size & power analysis calculator
  • Reduce sample size while still ensuring results are statistically significant
  • Non-standard test statistics for mid-trial Adaptive modifications

 

Powerful Sample Size Options

Use our sample size calculator to rapidly calculate sample size for a multitude of scenarios

  • Sample size calculator with 100’s of sample size and power calculation procedures
  • With Plotting Features, easily conduct a variety of “What-If” scenarios to align your final sample size choice with your scientific and budgetary requirements
  • Fine tune calculations with the Specify Multiple Factors tool

 

 

Share & Empower

Easily communicate calculations to your team

  • Share your work quickly
  • Fast and useful reporting tools
  • A sample size calculator that empowers your team

 

 

Easy & Intuitive To Use

Clean and fast spreadsheet style interface with no coding required

  • Zero manual coding
