A magical journey into knowledge creation in emergency difficult airway – Sample size calculation and choosing statistical tests with with research genie

This article is the second of a 4-article series intended to ignite the minds of readers and empower them to create new knowledge in the context of ‘emergency difficult airway access'. The aim of this series is to empower readers to create product/process/paradigm/position innovations in emergency difficult airway access for better care of humanity. The reader is familiarised with an educational smart phone-based application - Research Genie. The application has been designed and created by St. John's Medical College Research Society. The reader will be trained in a stepwise manner to use this application. Study design for each domain-specific objective is described. The most appropriate guideline to ensure quality of the study is stated. Explaining study designs using a domain-specific objective imparts ability to choose the most appropriate study design in a particular domain. Nine domains of healthcare have been explored namely description, laboratory range estimation, incidence/prevalence estimation, evaluating therapies, measuring costs in healthcare, critically evaluating new tests, measuring risk, correlating variables and describing experiences, perceptions and beliefs. Principles of sampling strategy have been explained in a simple and lucid manner.
