Mathematical errors were found in the sample size calculation for a cluster randomized controlled trial. This correction impacts the original study
Area of Science:
- Health Sciences
- Clinical Trials
- Biostatistics
Background:
- A previously published cluster randomized controlled trial (cRCT) has undergone re-evaluation.
- Mathematical errors in the initial sample size calculation have been identified.
Purpose of the Study:
- To report and address mathematical errors in the sample size calculation.
- To ensure accuracy in reporting trial methodologies.
Main Methods:
- Review of the original sample size calculation.
- Identification and correction of mathematical errors.
Main Results:
- Correction of the sample size calculation for the cRCT.
- The impact of these errors on the original study's statistical power requires further assessment.
Conclusions:
- Accurate sample size calculation is critical for the validity of cluster randomized controlled trials.
- Transparency in reporting methodological corrections is essential for scientific integrity.
