What are small, medium and large effect sizes for exercise treatments of tendinopathy? A systematic review and meta-analysis

Paul A. Swinton et al.

Summary: This study conducted a systematic review with meta-analysis to explore the effect size distributions of exercise therapies for different tendinopathies and outcome domains. The results showed that the effect sizes varied across outcome domains but were similar across tendinopathies. Threshold values for different outcome measures were determined, which can guide interpretation and further research.

Sample Size Justification

Daniel Lakens

Summary: This overview article discusses six approaches to justify the sample size in a quantitative empirical study and emphasizes the importance of considering the effect sizes for inference. Researchers can use the guidelines presented in this article to improve their sample size justification.

Denouncing the use of field-specific effect size distributions to inform magnitude

Emily Panzarella et al.

Summary: The study highlights the shift in interpreting effect sizes from popular benchmarks to field-specific distributions in recent years. Despite lacking a theoretical framework, this approach is increasingly adopted and discussed in methodological and substantial articles. The research aims to encourage researchers to interpret effect size magnitude based on the specific context of the study rather than the distribution of effect sizes in a field.
