The revised conclusion
After analysing a small data set, Jo wrote that a new method always improved performance. A peer reviewer noted the short study period, uncertain measurement and absence of a comparison group. Jo did not erase the results. Instead, Jo narrowed the conclusion, described the limitations and proposed a more informative follow-up study.
