Mistakes to Avoid for Accurate and Transparent Reporting of Survival Analysis in Imaging Research

Restricted Mean Survival Time for Survival Analysis: A Quick Guide for Clinical Researchers

“…The log-rank test can be used to compare survival curves; however, it does not provide an estimate of the treatment effect (i.e., magnitude of the difference in survival). Some studies present the median survival time or survival rate at a specific time as descriptive statistics that correspond to the log-rank test, which is not appropriate [ 16 ]. There are no corresponding summary statistics that present the entire survival distribution.…”

Research Highlight: How to Use Technical and Oncologic Outcomes of Image-Guided Tumor Ablation According to Guidelines by Society of Interventional Oncology and DATECAN?

“…Unlike the diagnosis/prediction of static binary outcomes, the follow-up time should be considered for survival analysis and should be defined accurately [ 7 8 ]. The commonly used time-to-event endpoints are presented in Table 3 .…”

How to Clearly and Accurately Report Odds Ratio and Hazard Ratio in Diagnostic Research Studies?

“…The odds ratio (OR) is a statistic commonly used to show the strength of association between test results (such as imaging findings) and the presence or absence of a disease in diagnostic research studies. Similarly, the hazard ratio (HR) is frequently used in diagnostic research studies to show the association between test results and events occurring over time [ 1 ]. Although these statistics are widely used in radiology research, it is not rare to see them described or interpreted unclearly or imprecisely in diagnostic research manuscripts, particularly at the peer review stage before publication.…”
