5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Good work,the authorscreated a prediction model and explain it in a clear way with an appropriate statistical analysis. Even if this work does not describe new concepts, it has relevance for its application in a contest of limited resources.

Reviewer #2: This study evaluates the effectiveness of a multiparametric model compared to a PSA-alone model in predicting metastatic progression in prostate cancer patients in Ghana. It’s a good idea to consider patients’ social economic status because clearly it could affect patient outcome. However, I do have several concerns.

1. The title, I wouldn’t claim “two novel mathematical models” because there are numerous prediction models using PSA, a lot of them even divide PSA into tPSA, fPSA…for more precise prediction. The PSA model is clearly not novel.

2. Method Section: The study design is too vague, and should be elaborated. Detailed information is needed on the inclusion criteria, such as did you only include newly diagnosed patients or also previously treated patients? Diagnostic method (biopsy? Surgery?) and criteria? What is the diagnostic method and the disgnostic guideline used for determine the outcome (metastasis), and how did you group patients into different outcome groups, and if the diagnosis is unclear how do you address it? Any exclusion criteria? What are the time points when you collected the data for the model, in the beginning or another time? In all, the Method section should at least have cohort information, inclusion criteria, exclusion criteria, outcome study design, statistic analysis, etc.

3. Judging from table 2, you clearly used 2 different cohorts for the multiparameter model and PSA alone model since the case numbers are difference, the information for these cohorts should be elaborated.

4. Other biological markers such as ALP, blood calcium and phosphorous levels are also important for PC bone metastasis, and have been used in prediction models for prostate cancer in multiple studies, maybe the authors should include these markers as well for a more comprehensive and precise analysis.

5. An external data validation with a new cohort is needed to evaluate the performance of this model.

6. Authors need to proof-read the manuscript carefully, to avoid mistakes such as using the same paper for citation #6 and #8. English language editting is also needed.

Reviewer #3: General Comments:

This research article titled "Predicting Metastasis in Prostate Cancer at the Time of Diagnosis: A Comparative Analysis of two Novel Mathematical Models in the Ghanaian Context" is well-structured, offers substantial insights, and emphasizes the importance of a multiparametric approach in predicting prostate cancer metastasis. The study’s focus on the Ghanaian context provides valuable localized insights which are often underrepresented in oncological research. The novelty of comparing a multiparametric model with a PSA-alone model adds significant value to the existing body of literature, highlighting the shortcomings of relying on PSA levels alone.

Major Revisions:

Descriptive Statistics:

Start the Results section with a table of descriptive statistics for the study population, including means, medians, standard deviations for continuous variables, and frequencies for categorical variables.

Provide visual aids like histograms or box plots for key variables, such as PSA levels and age distribution.

Model Performance Metrics:

Present a detailed table comparing all model performance metrics side-by-side for easy comparison. Include confidence intervals for each metric.

Include ROC curves for both models in the manuscript, ideally in a single plot for direct comparison. Discuss the visual differences in the curves.

Confusion Matrix:

Include confusion matrices for both models to show actual vs. predicted classifications. Discuss implications for false positives and false negatives.

Subgroup Analysis:

Conduct and present subgroup analyses based on key demographic factors (e.g., age groups, socioeconomic status, ethnicity). Discuss any observed differences in model performance.

Provide visual aids like stratified ROC curves or bar charts if available.

Expanding Methods:

Clearly define the inclusion and exclusion criteria for the patient dataset.

Specify how missing data were handled.

Detail how interaction terms were considered or tested in the multiparametric model.

Explain any steps taken to avoid overfitting, such as cross-validation or regularization techniques.

Ethical Compliance:

Provide more detail on ethical approvals, patient consent, and data anonymization processes.

Discuss ethical considerations specific to local contexts, like confidentiality and data sharing.

Minor Revisions:

Title and Abstract:

Consider making the title more concise (e.g., "Predicting Prostate Cancer Metastasis in Ghana: Comparison of Multiparametric and PSA Models").

Add specific performance metrics in the abstract. Highlight clinical implications and briefly mention limitations.

Introduction:

Discuss the potential economic and healthcare infrastructure benefits of using a multiparametric model in resource-limited settings like Ghana.

Expand the literature review to include other multiparametric models used globally and their impact.

Statistical Analysis:

Provide a brief explanation of the Hosmer-Lemeshow test used to assess model fit.

Discussion:

Elaborate on the reasons why the multiparametric model outperformed the PSA-alone model.

Discuss how the findings can lead to changes in clinical practice, such as more targeted use of imaging tests.

Be more explicit about the limitations of the current models and propose how future studies could address them.

Conclusion:

Summarize the main findings and their implications succinctly.

Reinforce the call for implementing the multiparametric model in clinical practice.

Technical Aspects:

Check all citations for consistency and completeness.

Ensure that all tables, figures, and equations are consistent in formatting and clearly labeled.

Review the manuscript for excessive jargon and aim for clarity, especially in technical sections. Break long paragraphs into smaller ones.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
