Description

Description

Objectives: To review the concepts of odds ratio, relative risk and hazard ratio and to identify accurate ways to extract the effect measures, analyse and report them for randomized or non-randomized trials. Description: Reporting the effect measures correctly and accurately can be a challenge for some authors. Moreover, distinguishing the correct estimate to report for randomized and non-randomized studies can be confusing for authors who are not familiar with epidemiological studies, and advanced bio-statistical methods. I would explain the basic concepts behind understanding these measures. I will then explain what are the differences between un-adjusted and adjusted effect sizes. I will simplify the concepts of linear regression, logistic regression, Poisson, Cox proportional hazards, time-series and longitudinal analysis. And will explain how to select a correct estimate to report. The workshop will be useful for those who are interested in observational studies as well as interventional studies. If you do NOT like statistics, this meeting could be a good start for you!
