Additional Editor Comments (if provided):

Your revision is still in need of both minor and major improvements. I have itemized these in detail and made a number of suggestions for your consideration:

Current title:

Socioeconomic determinants of schistosomiasis infection using multiple correspondence analysis among rural western Kenyan communities: evidence from a schistosoma mansoni household-based research.

Suggested title:

Socioeconomic determinants of Schistosoma mansoni infection using multiple correspondence analysis among rural western Kenyan communities: evidence from a household-based study.

Throughout this article the term schistosomiasis is still being used instead of S. mansoni. The full term Schistosoma mansoni should be used in the title and the first time in the Abstract and in the main text after that it should be abbreviated to S. mansoni.

Lines that need to be corrected include

Abstract Line 6, All table titles 1-4.

L76, 84,85,86, 97,102, 106, 116, 287, 305, 418, 438, 476, 478, 449 (S.Mansoni)

Please note the ‘S’ should be capitalized, the ‘M’ should not be capitalized, on several occasions the lower case ‘s’ or the upper case ‘M’ was used.

ABSTRACT

BACKGROUND

Line 5 (MCA)can without a space should read (MCA) can

Please state what was the original hypothesis? Presumably that MCA would be a useful predictor of S. mansoni prevalence (and/or intensity)?

METHODS

Line 3 ‘over the years’. How many years?

You describe a sample size of 600 but your Figure 1 in the main text describes 50 adults per stratum. Please explain. Are the 50 adults only those interviewed? If so please edit the title of Figure 1.

The main text describes taking urine as well as stools but no mention is made of those findings for S. haematobioum.

FINDINGS

Where is the comparison by strata: Hotspots vs Responders?

I don’t think you do justice to your findings by only reporting on the significances by prevalence using the multivariate analysis. I think the general reader will want to put that into perspective by understanding the significant higher prevalence in males, younger age group, unsafe water source, region and occupation (fishing).

You make no mention of significant findings by intensity of S. mansoni infection which was higher in males, younger age group and region.

When stating the lack of significant by prevalence it is really important to draw the readers attention to the wealth quintiles only spanning poor and less poor.

CONCLUSION: This need to relate to the original hypothesis such as:

The MCA model was not an effective predictor of S. mansoni prevalence and or intensity. Perhaps the study populations were not sufficiently dissimilar?

These comments refer all to the main text which would be better presented in a more concise manner. In the METHODS Line 173-181 seem better suited to BACKGROUND.

Minor comments:

Line 120 ‘other’ should be replaced by ‘another’

Line 121 ‘Convenience’ sampling for what stool sampling or interview?

Line 125 in missing a ‘.’

Line 147 Urine should be urine

FINDINGS

No S. haematobium results presented. What happned to the urine samples?

LIMITATIONS

Small sample size of 50 per stratum

Convenience sampling

CONCLUSION

Lines 457 and 462 ‘Contrast’ would be more appropriate than ‘contradict’

This is far too long and mixed with recommendations about poverty alleviation which is not based upon the MCA FINDINGS as presented.

Additional Editor Comments (if provided):

You need to pay much more attention to detail and every comment made by reviewers.There are far too many typos and presentation weaknesses. Your background, methods and spill over into results augments around which method (MCA versus alternatives) to use is too long and repetitious. State your rationale for using MCA in a more straightforward manner once only. The next issue is the sampling method? The Abstract said random but the main text says convenience on more than one occasion. Please clarify how many samples were confirm positive on CCA only and how you adjusted for intensity in that instance. The conclusion need to be concise: MCA was/was not a good predictor for S. mansoni in this setting.

Reviewer #2: 1. The entire paper is filled with grammatical errors, including the title.

2. What evidence do you have about schistosomiasis as a social disease (Line 10)?

3. Where is the evidence for recall bias in creating SES (line 50 & 51)? Cite the reference

4. What do you mean by this statement, “urine samples were used to investigate S. mansoni” (lines 155-159)?

5. Repeated definition of acronyms even though they have been defined earlier (Line 73).

6. Did the STH and urine data included in the analysis? If yes, report on the findings; otherwise, briefly state that STH and urine data are not reported in this paper.

7. Results interpretation is not clear. For instance, you could say S. mansoni infection was 1.42 times higher or lower in hotspot villages when compared to responder villages. You have to be consistent with the interpretation throughout the result section.

8. What do you mean by “infection prevalence” (line 320 & 337)?

9. What level of significance do you consider as “marginally significant” (lines 356-358)?

10. The entire discussion section needs to be looked at again. The section did not address the possible reasons for significant or non-significant associations with the predictor variables.

Reviewer #2: Abstract

Line 20: Are you referring to “indicators” or inductors? Please correct if you are referring to indicators.

Materials and Methods

Line 161: Please if you are using “schistosomiasis” throughout the text continue to do so otherwise change “Schistosomiasis” in line 161 to “schistosomiasis”.

Line 136: Delete one “the the”

Line 303 – 304: You already defined socioeconomic status as SES please use the acronym throughout this text.

Results

Line 339: was there any significant difference between the study participants (males versus females). Please say so if any difference was observed.

Lines 357 & 358: Please rephrase this sentence “males were associated with 1:43(95% CI=1:18-1:73) times higher prevalence…..” I think it should read as “males were 1:43(95% CI=1:18-1:73) times higher prevalence compared to females”

Line 389: Again, please use the acronym (SES) for socioeconomic status

Lines 419-421: please correct the grammar in these sentences. It will read better as “….. that the EPGs among those aged below 30 was significantly higher as compared to those aged between 30-60 years and above 60 years.”

Lines 423-425: Same comment as above.

Line 427: Again, please use the acronym (SES) for socioeconomic status

Discussion

Lines 467- 470: Please define the acronyms LF, HAT, VL and NTDs you are using them for the first time.

General Comment: Please do a grammar check again especially in the area of subject verb agreement, use of prepositions and sentence structure.

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.
