Round 1

Reviewer 1 Report

This article reported the protocol of the Long-CoViD patients causal diagnosis and rehabilitation randomized feasibility controlled trial in patients with Dysautonomia, which is an interesting topic today and well done. However, some concerns in this article need to be addressed.

1.      Please write keywords in a consistent format (first letter).

2.      In the first citation, put the full name before the word abbreviation, followed by the abbreviation (e.g. covid-19). Please correct.

3.      Use lowercase letters at the beginning of words in sentences.

4.      Please enter your questionnaire as a supplementary file.

5.      On line 40 add the WHO link for your reference.

6.      Please use the WHO link instead of reference 5.

7.      Please change Long-CoViD to Long COVID.

8.      For better understanding, please explain the abbreviations in Table 1 below.

9.      Please discuss further and improve in the discussion section.

10.   Research limitations and suggestions were not addressed at the end of the discussion. Please include these.

11.   Update the references.

 Minor editing of English language required.

Author Response

Thanks so much for the feedback.

1)Changed to alphabetical order

2) Didn't quite comprehend- is there a need to refer to coronavirus disease 2019 (covid-19)? Didn't change anything there as covid-19 is widely used.

3) Do you mean that we should change the first letter of each sentence from capital to lower case?

4) Demographics questionnaire included as supplementary

5) Added as a reference too

6) Estimate was not found as an official WHO site/ statement but as referenced by Dr Wise in his BMJ publication, as referenced

8) Abbreviations included

9) Discussion was extended

10) Done

11) Done

[60]...".  Lines 243 & 244, "...into blocks of 4 & 6.  A separate study ...".  Line 247, "physiologist or the physiotherapist and ...".  Line 261, "... and physiotherapist; and personalized ...".  Line 263, "... recommendations for any post covid-19 ...".  Line 264, "... with advice for 2- 10 min practice ...".  Line 271, "seated row with increasing wait and ...".  Line 272, "... former studies (Fu & Levine, [62]), so as to ...".  Line 283, " ... can withdraw at any time."  Line 284, "... regarded as an AE, such as fatigue and ...".  Lines 292 & 293, "... that would meet the experience needs and ...".  Lines 312 & 313, "... dysautonomia and to build upon interventions ....".  Line 322, "feedback and live experiences in each phase of ...".  Line 326, "... intervention so that a greater multicenter ...".

Well written; however, the manuscript has some editing issues.
