How to fill out Sample size determination in health studies - A Practical Manual

1. Identify the primary objective of your health study.
2. Review the type of study design you will use (e.g., cohort, case-control, randomized controlled trial).
3. Determine the expected outcome or effect size you wish to detect.
4. Establish the significance level (commonly set at 0.05) to determine the threshold for statistical significance.
5. Decide on the power of the study, typically 80% or 90%, which reflects the probability of detecting an effect when there is one.
6. Gather necessary estimates such as variability and dropout rates from prior studies or pilot data.
7. Utilize statistical formulas or software specific to sample size determination for your study type.
8. Adjust the sample size for potential non-response or dropout rates to ensure adequate power.
9. Finalize the sample size calculation and document all assumptions made during the process.
