PONE-D-23-00139How many days of continuous physical activity monitoring reliably represent time in different intensities in cancer survivors?PLOS ONE

Dear Dr. Western,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Apr 10 2023 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Yes

Reviewer #2: No

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

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: This is very interesting study evaluating the number of days with >/= 22 hours of accelerometer wear time needed to evaluate PA in cancer survivors. I have the following questions for the authors that should be addressed in the manuscript:

1. Why wasn't cancer stage, treatment history, and time since completing treatment considered in the analysis? If the data is available, this analysis and findings should be included. If the data is not available and explanation for why it is not available should be included in the manuscript.

2. Conclusions should be revised in order to be specific to the time relevant in the cancer care continuum and cancer type to which this data applies. For example, "Only two days of wear time is needed for LPA in breast, CRC, and prostate cancer survivors at least 2-months post-treatment."

Reviewer #2: There is misunderstanding in the Spearman-Brown formula. K is the ratio of number of new additional days, to the original number of days. So k=6 is actually 6x6=36 days in total. If the authors want to test how many days within 6 days, k should be 1/6, 2/6, …, 6/6 instead.

The analysis needs to be performed again and conclusions needs to be re-written.

To fully understand the variation contributions (intra- or inter), a linear mixed model for longitudinal analysis should be considered. A mean plot by each day and characteristic groups can be illustrated. Furthermore, Bland-Altman plot may be considered too. The authors may consult with a statistician.

ICC better presented with 95% confidence intervals.

In several places, “Analyzes” should be “Analyses”.
