Turn any 2ร2 table into a result you can word correctly and explain to anyone, by understanding it rather than memorising it.
You will leave with:
- A correct 2ร2 table every time, with exposure in rows and outcome in columns
- One right sentence for each result, such as 'twice the risk'
- The step from relative to absolute effects: risk difference, ARR and NNT
- 9 video lessons and 1 written lesson (about 1 h 12 min) and a final quiz
- Lifetime access, to come back to for any exam or analysis
Who it's for: students preparing for epidemiology and EBM exams, junior researchers analysing their first data, and clinicians and pharmacists who read results sections and want to explain benefit and harm to patients.
