A comparative study of hematological parameters between hypertensive and normotensive individuals in Harar, eastern Ethiopia.

PLOS ONE

Dear Dr. Gelan,

Your manuscript has now been reviewed by two referees who have raised concerns over the lack of detail regarding the sampling technique, as well as the definitions for hypertensives and control patients. There is also some ambiguity over the number of males and females in this study. Since this is fairly important information I invite you to submit a revised version of the manuscript that addresses the points raised by the reviewers and includes the needed information.

Please submit your revised manuscript by May 21 2021 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: http://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.

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: 1. Authors did not show how they calculated the sample size. They should explain how they got the sample size.

2. Authors did not state the number of males and female in both cases and controls. This should be stated in the manuscript.

3. The sampling techniques was not well described in the methodology. The mention of convenient sampling is not enough.

4. The criteria for selecting the controls is not clearly described in the methodology section. Authors must describe this.

5. The operational definitions for the cases (hypertensives) and controls (normotensive) are not stated clearly stated. Authors must describe this.

Reviewer #2: I have read your manuscript with interest. In general, the paper addresses an issue that admittedly needs more study and attention. This is a manuscript where the authors examined the "A comparative study of hematological parameters between hypertensive and normotensive individuals in Harar, eastern Ethiopia".

1. While appreciating the challenge of preparing a manuscript in the English language for many authors, the paper should be carefully edited by a native English-speaking editor.

2. No information about the physical activity records.

3. Please explain more about the implication of this study results. How can the study results help clinically?

4. The Discussion would be improved by detailing more specific implications for future studies.

5. The limitation of the study should be fully explained in the discussion section.
